Help with Z-Offset Adjustment Magnetic Probe at High temps

Hello all, I need some help here. I have klipper installed on an anycubic kobra 2 neo with the stock mainboard. I have been able to tune everything in quite nicely with PLA and with PTEG filaments. when printing with PTEG I have had to add conditional Z-offsets into my start print marco due to the magnetic probe and the heat from the print bed. what it does is adjust the z offset down by 0.1mm which has been working perfectly fine.

Now I am trying to tune thing with ASA filament for printing some upgrades for automotive use. my problem is that with a bed temp of 115c I have had to adjust the z-offset further down to -0.65mm just to get the first layer to lay out on the bed without it printing in the air and balling up on the nozzle.

the problem is with the stock probe on the kobra 2 neo not liking the heat. I have thought about different probes but I have no idea if I can change out the magnetic probe with something like a BL Touch or a clicky probe with the stock mainboard and get away from having to use conditional z-offsets in my start and end marcos.

I first discovered this issue back when I still had the stock firmware on the printer and I couldn't level the bed properly trying to print with ABS and PTEG. since moving to klipper I was able to get it leveled.

I have klipper configured with KAMP for adaptive leveling. is there anything I can do to minimize the effects on the probe from heat or a simple way to switch to a different probe without having to replace the mainboard?
