The key is to advance your h-pawn as far as possible quickly (starting with h4 on move 1) to give us as much space as possible so their pawn is further away. Eventually, you can block the opponent King (and pawn near it) by King opposition and such (look up King Opposition) if this is new to you. Sooner or later, Black's King will have to go after your h-pawn to try for making progress. You then have a basic theoretical draw by getting your King into the promotion corner.

p.s. Two comments:
1) Move 2 should say "b-file" not "-bile" silly autocorrect. I am like 100% sure I typed it correctly.
2) Also funny how I'm realizing how many exclamation points I used and how the pgn spaces them all automatically in formatting; probably to distinguish from "!" chess annotation for an Excellent move lol

puh, very complicated. I just thought: First you put your h pawn near the center to prevent the oppisite pawn to get too near the queening place. 2.) I treat the black past pawn like I learned it for the pawn and king vs. king endgames (because as long as the King is with this pawn and the other pawn is stoped at the middle of the board it is exactly that situation). That means stay in front of the passed pawn, don´t let the enemy king go in front of his pawn, always take the oppisition if possible.)
3. as soon as the black king goes in the direction of my remaining pawn, eat the passer and go to the same direction. A rook - pawn is easier to stop than other passed pawns. And its crucial not to let the enemy in front of his passer.
Hello
I have no qlue how to solve this for a draw for white. I can´t prohibit black to get a queen.
How do I have black king to give up the b4 pond?
