I am not entirely sure what "configs" you are referring two, but there are only two possibilities I can think of right now, so I'll try to explain them both.
1. If you are trying to "preview" moves in a daily game, there is an analysis board that you can access by pressing a button that looks like a magnifying glass looking at the checkered pattern of a chessboard. The analysis board there allows you to move pieces as you please, which helps you to analyze the position.
2. If you are referring to the arrows in live games, which now that I think about it is more likely since Hikaru doesn't really play daily games, you can hold right click on any square and drag it to the square you'd like the arrow to go to.
Hope this helps!
how to get the configs like hikaru nakamura to preview the move
