Steam Input is super helpful with this. If I find that I'm consistently pressing wrong buttons on the controller, and the game doesn't give you the ability to rebind controls in the menu (ew), then I just edit the profile in Steam Input and voila
People sleep on Steam Input, but it's one of the more unsung features of the Steam Deck imo. Nobody ever talks about it, and I've even seen people say that they hate it which makes zero sense to me (just don't use it?)
