Extract the 16MB bios region from the bios update, find another dell bios model that uses the Ice lake chip, copy the bios region over ,clean the ME firmware. It should use the same boot guard and if the OEM configuration is the same it will work. If the OEM configuration is different it will not boot at all or work partially.

I tried this first, but the flash image tool wouldn't let me install it, even though they were the same ME versions. I also think the CSE region partitions wouldn't work either. If that worked partially, I thought I could update it from the BIOS.
