Does anybody know if there is a way to increase the deadzone on a joystick? For the handle twist in particular here.

The handle twist on my joystick is slightly broken, so it will lean just about one millimeter to the left when I rest my hand on it.

It is extremely tiny but enough to be registered. I myself however does not notice such fine tuning, so I would be perfectly fine increasing the deadzone to above this millimeter or two.
