Can you verify this using the verification tool? Reports on the internet say the tool reports machines with earlier generation processors are being flagged as not compatible. I don't have any i8 or later CPUs to test with, but thus far all of my machines with TPMs have reported as not compatible from Microsoft's tool. https://aka.ms/GetPCHealthCheckApp
Here's the actual compatibility doc. https://docs.microsoft.com/en-us/windows/compatibility/windo... TPM 1.2 is the bare minimum required, TPM 2.0 for some security features That's a very far cry from "8th gen Intel required", TPM 1.2 has been around for more than a decade. Odds are you need to change a setting in your BIOS.
This link says TPM 2.0 minimum:
