Need ability to map the R3 button on ps4 to nothing! Please

For people like myself, who when in a close quarters battle I always hit the R3 button. I've been playing for years, and I just put to much weight on the right joystick in certain situations. Now there is no ability to avoid mapping the R3 button, because the quip wheel now comes up. I've tried every other combo, and they all cause a loss in close quarter battle due to affecting me during batttle(ie: changing to single shot, slowing me down because I pinged something, arming grenade, pulling up quip wheel, or throwing a kick or punch when Im 20 feet away from guy/girl buzzing down for the kill, and I always get killed) super frustrating. It would be nice to be able to map the R3 to nothing, that would solve the problem, and shouldn't be a very hard fix. The game is already hard enough for me, and now it's almost unplayable due to the high skill level of other players, one mistake and your dead.

Thanks, and hopefully you understand I am just looking for a fix
