Considering Upgrading Optiplex 7050

I have been receiving this message from pc health check. " The processor currently isnt supported for Windows 11". I have looked into reliable workarounds and haven't found any. Since this computer is somewhat new, I want to avoid buying a different one. Would I be able to upgrade the cpu on my optiplex for cheap? I have 2 computers, one with a 6700(HP) and 7700,
 that I would like to upgrade to windows 11. Thanks
