Hi, @Vic_Banner 
Thanks so much! So I was able to (seemingly) successfully flash your modded BIOS, which now shows an active TPM! Alas, the BIOS is no longer recognizing my 3550H DMAF5’s standard M.2 drive where the OS is installed. Any advice? Is this something that can be worked around or do I need to just swap in a different boot disk and flash a different BIOS?
