I recently bought an Ender 5 Plus, but lately every print the bltouch sensor randomly turns on, extends and then goes into alarm mode. It cycles through every few minutes and it hits the print. The firmware locks up and does not let me leave the "Adjust" screen anymore, print process updates also break. I have to unplug the sensor to stop it hitting the print breaking it.

There seems to be a screw in the center of the sensor, I turned it both ways and checked the effects, but even nearly unscrewing it anticlockwise did not yield better results. I tried contacting Creality, but no luck so far. I am planning to replace the board and firmware of the printer in the near future to go along with a new hotend, last thing I want is to break all that with a bad sensor.

Is there some guide on how to tune the set screw properly, what I should look for?
Is the sensor just bad and I should get a replacement?
Is there some gcode to perhaps turn off the sensor entirely during print(frankly the constant red light is annoying) or can I configure Marlin to unpower the sensor during print?

The new board is a SKR 1.4 turbo with a TFT70. Hotend will be a micro swiss direct extruder hotend kit, but I need to get the printer working reliable first to print new fan shrouds for that.
