Controlling capacitive touch panel on a stove
What you need to do a wtich the sensitive part of the deviuce to ground when you want to sense touch and have it open for no touch.

You can maybe use a mosfet or transistor to ground, but it might take a relay.

The one with the JFET connects to VCC (the microcontrollers positive locig voltage) so that it can switch.  There's plenty of capacitiance between the positive and ground.

A fifth option is just to connect a GPIO pin directly to the pad and set to output (high or low will make little difference) to activate the touch sensor and to input to deactivate it.
