Default Guidance to pursue a hardware-changing system app

Hi XDA!

This is my first post here. I need some guidance on making a system application that is capable of disabling a particular hardware component device. I don't know if it is possible or not, but I need a direction towards this. Even if it isn't possible, I would be grateful if anyone can guide me atleast close to this. I know making basic android applications and am interested in making apps that have a much more stronger hold on the device. Also what knowledge and experience do I need to be capable to explore this area.

tl;dr: need a direction and advice to make a hardware disabling system application

Any advice is appreciated.

Ciao!
