You have to download GenSMBIOS (google it) and select your config.plist in your USB EFI folder. To generate a new SMBIOS you must write the model you want, I used MacBookPro13,1
Sorry if it was a basic question, I'm really new to this world.
I followed your solution and chose a supported smbios and finally have a new Monterey up and running smoothly.
Thanks for the support, much apreciate it.
