Ok read the documentation: …microsoft.com/…/windows-11-24h2-supported-intel-…

Where does it say that you can use a 6th gen Intel CPU if you install a tpm chip?

The tpm is definitely not used as you can install it on a supported system, then go to the bios, disable secure boot and tpm and it still works (if the automatic “ransomware” bitlocker encryption didn’t start)
