MH Wilds Config question

Long story short, I prefer handheld gaming. I love Monster Hunter and found this mod:

Now, I think i can handle it but I’ve never really used the deck out side of the steam games that it runs well.

Can anyone tell me if I make these changes, is it just FOR THIS GAME, or will I need to convert the settings back for my other games like Marvel Rivals, or Kingdom Hearts?
