Hey guys I have a 2017 iMac eemc 3069 . I have managed to read the bois chip .  This machine is locked with efi password as well as an MDM profile so i need to edit serial number as well . I have a clean serial off of a dead board . I was told if i write the serial to the chip I wiould need to clean the ME region on it as well.  is this the case ? if anyone could help I dont mind paying. I have uploaded my dump as well . thanks

Actually you just need to change serial number and remove data for EFI in bios dump, no region change required.
