You are the absolute man!!! Will set out to do this tomorrow. Thanks again!!!You definitely need to update the BIOS version to F12j which has the easy CGF lock/unlock setting. Apart from that change, the rest of the settings are pretty much the same as before. Just incase, Enable 4G as well as VT-x and you should be good to go.
Here is my EFI Folder in it's entirety minus personal data also BIOS pics of CFG lock/unlock.
I am using iMacPro1,1 Mac model as I do not have integrated graphics which serves well to enable Apple TV+ but with your CPU, iMac 19,1 would be better suited. The EFI Folder will still be fine for you with the appropriate changes in the config.plist - Good luck.
