How to set nvidia card as primary?

I am looking to play payday 2 and I wanted the game to work with the Nvidia card is this possible? I know the game doesn’t recognize my second monitor, which is weird. And in the SET LAUNCH OPTIONS I put DRI_PRIME = 1% command% as it says in: 7567/16597/15

Anyway, am I doing something wrong? I would very much like the nvidia driver to work for this game.

DRI_PRIME is for AMD cards only.
Can you post the output of theses 2 commands please
