yup. Fixed list of supported cpus. Well, I suppose it grows to include newer CPUs.

That said the rufus workaround can work for these - I'm writing this from a machine that's not a supported cpu that I just upgraded to Win 11 with rufus. Runs just fine. Fun fact about my cpu: no cpu with the same socket is supported, so to be officially supported I'd have to also upgrade the motherboard.
