M-Audio Axiom Pro 61 Aftertouch & Sliders Issues

My Board has several weird things going on with it, but the main issues are that the aftertouch is always registering, and the sliders either don’t work at all or move a majority of them on the screen. I’m wondering If I would be able to disconnect these functions to just use the key bed, pitchbend and mod wheel, while using a nano kontrol in place of the buttons and sliders
