CR Touch + Nebula Pad + Ender 3 (4.2.2)

Good evening all!

New to 3D printing and have had the Ender 3 4.2.2 motherboard for about 2 months now. I decided to upgrade to the nebula pad for the camera features and was able to get it to work by selecting the Ender 3 pro firmware.

My issue is now that i have installed the cr touch i can get the darn thing to calibrate. how do you set the Z offset?

Anyone have a solution to this> THining abouy just going back to the z switch and no Bl touch!
