Curious I tried the normal Win11 setup (created the USB bootable image using the Media Creation Tool) without proceeding any further. Looks like you can accept the warning that your CPU is unsupported (assuming everything else is supported like TPM/Secure Boot etc). It does say you are then not entitled to updates, but I would think you will still get them surely, just that because the CPU is unsupported, you're not "entitled" o them in the definition context?
I'll wait until the 5th before using the MCT again and letting it get the final version of Win11 then do the upgrade assuming there is a final build different to this current release channel build of course.
