In the most common configuration when a endstop is triggered it goes open circuit, when an endstop is disconnected it goes open circuit, ... see the issue?
It can't tell if its triggered or disconnected.
You cant disabled it, but you can trick it so then when its open its not triggered
eg In marlin find
// Mechanical endstop with COM to ground and NC to Signal uses "false" here (most common setup).
#define X_MIN_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop.
#define Y_MIN_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop.
#define Z_MIN_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop.
#define X_MAX_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop.
#define Y_MAX_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop.
#define Z_MAX_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop.
change any that are triggered to the reverse of what it is now (true becomes false,and false becomes true)
Or if you can simply use a jumper and short the S and - pins of the endstop.
DO NOT short the - and+ pins, you will instantly kill the voltage regulator (you have been warned!)
If its a ramps I direct you to the folloing Image where the S - and + pins of the endstop pins are clearly labelled (click image a few tome to zoom in)
