Unless you've Morphy level talent it won't happen. Of course you should keep trying.
Beginner to ELO 2200 in year

That's virtually impossible. Magnus Carlsen managed to increase his grade by 900 in a year around the year 2000, and that was a period of intense strudy guided by a chess master. You are aiming to increase your grade by about 1100 with less time and without a professionsal coach. For you, a reasonable aim in a year would be to reach 1600, and even that will be a serious challenge involving many hundreds of hours of both study and play.

Your biggest problem is the dog. You can quit your job and spend zero time with your family, but you have to go for a walk with your dog every day for at least one hour. This will cost you a lot of ranking points!

I dont think you are aware just how much time you have to invest...I also think that you are probably trolling...leaving family and job to pursue a life of chess...thats a sign of trolling...either that or you are not stable in the mental department
... chess is not worth giving up your job, divorcing your wife and leaving children without a father; ...
... This part was an ironic, a joke ;-)

Of course he is trolling...

At least you wouldn't get your neck broken by the wife.

Personally I don’t think a 10 million dollar prize and unlimited resources would make as much difference as you think, because it wouldn’t be any substitute for the necessary experience.
I wish you good luck though and curious to see how you get on.

Just an idea...
What do you thing would happen with your perspective about the challenge if would have said the same things but with this fictitious scenario...
- If I win the challenge I get a 10 Million US dollar price.
- I´m going to move with my family, my dog and my kids to a seven stars High Performance Center wherever we choose.
- I have a top preparation team:
A team with 7 top chess coaches (Dvoretsky is the leader of the coach team),
A mental coach
Medical team with an expert in ergogenic drugs
Sport and Conditioning Coach
A very good chef with a strict nutrition guideline
And all the best equipment needed for a super preparation and recovery
- All the leisure activities we want for me and my family.
- And so on...
Just one year - ELO 2200 or more
Do you still have the same perspective?
Unfortunately, even a 10 million dollar prize won't make your brain work differently. On the other hand, if you are able to revive Dvoretzky, then reaching 2200 should be a walk in the park.

OP,
Technically it is not impossible. You would only have to play one OTB tournament and perf at or above 2200.
That is a performance goal. As all of your opponents also have a vote, these are sometimes difficult to nail as a one off, which is why it takes experts up to 10 years to gain 200 ELO points.
What you will need is several process goals. These are not so difficult in themselves, but they take time and I assume you don't want to end up homeless, so they have to be realistic. I find that any hobbies at our age that start to take up more than two hours a day begin to impact lifestyle. You have to be honest about what you can commit to. Know where your D-1 is. D = divorce and 1 is time in minutes.
Examples could be study 12 quality chess books. My System ,Reassess, Life and Games f Mikhail Tal...etc. You have a year, one a month seems realistic.
Maybe solve 15,000 chess puzzles. That is a little over 50 a day. I recommend chesstempo.com it keeps stats and there are way more than 50,000. CT-Art on your phone too. Unfortunately 50 a day could take 5 hours so either go deep and solve less or go quick and solve more and hope you learn the patterns.
Maybe Play one long game 5 or 6 days a week a day on chess.com and then analyse it through some kind of chess program. 30 min a side,
Learn 4 openings. Two white, two black.
For performance goals, In order to get close to a 2200 national federation ELO you will probably need a 2400 chess.com rating. If you get to 1600 in a couple of months then maybe you have a shot at it.
So, 1600 by March, 1800 by June, 2000 by September, 2400 by December
Then play the next big Open tournament. It has to be Open though, not a Sectional Swiss tournament.
Anyway, it will be monumentally hard but lots to blog about. Also better than that clown who thought he could beat Magnus after having his computer think for a month.
It's the process that matters. If you end up at 1600+ I would consider that a win.
Good luck.

you could try becoming a leprosy carrier, causing all your opponents to die before the end of each game.

No online rating means too much as there as so many variables and in any case, ratings themselves aren’t an absolute measure of strength, they’re just a measure of how good you are within that specific player pool.
OTB ratings tend to be far more reliable, you’d need to play plenty of OTB anyway if you hope to make serious progress.

Thank you for your answer. There are several ideas you have mentioned, I need to think about some days.
But to finish the challenge with several OTB tournaments makes a lot of sense.

fictitious scenario

i have seen your home page, rating, positions and even your 19-0-1 record in your last 20 games. Without an engine you have zero chance of reaching even 1700 within even 3 years.

I went from beginner to 1700 in about 4 years. Certainly possible.

I´m a beginner... yes. But that is not a problem for me, i feel great being a beginner in chess ;-)
I have been a beginner in many fields or executing many tasks - as all of us-, and I have master the one that interested me -as all of us who have pay "the price" for it. The challenge is about trying to improve from my level to advance in a certain period of time.
I have no interest in using an engine for cheating myself or others. That makes no sense for me.
At least you wouldn't get your neck broken by the wife.
