Cant get Monterey to work on Fujitsu D556/E85+

[Feartech]

so I do have Catalina up and running and I'm looking to upgrade it but I do have an issue with Catalina as well. the system won't boot without the usb macOS installer stick. I have gone through forums and have tried almost everything I could find but I still can't get it done. tried copying the EFI folder, new installation but no luck. could that be an issue preventing me from upgrading?

possibly
