Oversensitive Home Button- can I recalibrate or disable completely?

I dropped my iPhone last week and, as a result, the home button has been oversensitive. So sensitive, that even when I am outside, the wind causing the whole screen to glitch and think that I am going in between apps and exiting out of apps even when I am not touching the screen.When I am indoors, the home button just stops working completely and I am forced to use assisted touch. I am wondering if there is a way to completely disable the home button so I can just use the assisted touch? Is there any other way to recalibrate the home button? Any help would be amazing.
