There is (of course) a registry hack to disable TPM checks
When I use W11, I use it as a Virtualbox guest....but VBox doesn't yet do TPM pass-through, so although I have a full TPM 2.0 chip on my Desktop, the W11 guest on my KUbuntu 22.04 can't see it yet...VBox 7 is supposed to fix that.
In the meantime, there is a Registry (shudder) hack to disable both the TPM and the Secure Boot checks, and allow upgrades. I won't post the links, in case it gets El Reg in trouble - or me with them! - but they're easy to find with Neeva (yes I use Neeva to avoid Google, and I run it on Opera and Brave), and trivial to set up....if you don't mind using regedit. The primitiveness of still having such an awful thing as the registry is staggering in 2022....but windoze still has Pagefile.sys and many other anachronisms from the 80s and 90s. Sorry - a personal hobbyhorse! The point is that you can use W11 without TPM and secure boot. I just can't see any good reason why you would want to.
