How can I adjust my horizontal sensitivity not ADS sensitivity only.

There’s wayyyyy too many settings on this game which don’t think is a bad thing but just complicates it. I can’t find simple settings such as horizontal sensitivity, I was able to adjust it when the game first made me choose my settings and all that but I can’t find it. Only if they had an option to simply switch your front triggers if you wanted to shoot with the top ones. I’m just trynna play the game but these settings are too much
