Flipped\inversed orientation on vr

Hello.
for a small project i’m doing on university, i’m building a game and i’m trying to flip the orientation\world in the hmd, as if our brain didn’t correct the z axis rotation. The problem is that the camera rotation is not enough, i need to rotate the entire screen 180 degrees because i use hand tracking in the game.
the orientation option in the player settings isn’t helping me because landscape right makes a very weird outcome. Thanks for the helpers!
cheers
