HP Z840 Windows 11 CPU compatibility

Hi

I have HPZ840 

I tested Windows 11 on it and love it the only issue I bypass the installation and as far as I know Microsoft not going to update your system if you bypass.

I tested the system for compatibility with tool called WhyNotWin11 and the only thing that NOT compatible  is the CPU everything els pass.

I wander if any one knows if any 8gen Intel CPU’s and above compatible with the HP Z840?
