That's a later thing. Remove the EFI from the USB. Keep booting using USB until its ready.

Okay. It's obsolete now. You'll need to change SIP in the config.plist and then run OCLP and install the Legacy Graphics patch and you should be good to go.

Also, HD7770 is supported up to Monterey. So install the GPU and then check if you have acceleration. WEG and boot args are required.
