[HELP] Cant boot to installation menu. "Unable to validate dell smm signature not loading smm sensors."

Hey all,

I've been trying for the last few days to get my system to even boot to installation but I can't figure out the issue.

I`ve done the Vainilla Installation guide and tried both Virtual and SMC kexts, with 18,1 and 18,2 in smbios but I got no idea of what i´m doing wrong.
