It’s right above the left/right lean mapping options. Select it and hold Y (for Xbox) and it will disable it.

Edit: keep in mind you won’t be able to hold your breath for sniper shots unless you re-map that too. I didn’t cause I don’t snipe.

Also if you're going to use L3 for leaning, make sure you rebind hold breath (for the scopes) to something else - e.g. one solution is to map it to the zoom button so you auto hold breath on ADS

I have searched the menu in settings everyday for the past week and can't find where to map the lean options on Xbox.. please help!

It is the Options Control Schemes screen where you remap any of the rest of the actions/buttons in the game

Do you have a screenshot because I swear there's no options to map buttons for me under control schemes, it just shows me the different control schemes.

right there. customize your control scheme
