ps4 controller button request

let me disable the right stick pressed in, during a fight my right hand clenches and the thing bound to the right stick pressed in goes off and its bad enough i can't play wattson with the ps4 controller. let me disable the right stick pressed in please.

as caustic ive had my fair share of these moments for my poor enemies, see my gas barrels are bound to my right stick press in and i throw them when my hand clenches instead of firing so i throw my barrels and it gets a lot of kills by  accident! i got 12 the other day i never get 12 kills, so sad 4 my enemies who might think im gud and im just clumsy;
