    The only thing I didn't do, pretty much, was enable Secure Boot. I don't know if TPM will actually work correctly, because even when this is a brand new Windows 10 21H2 installation, I installed Windows 10 with the Ryzen 7 3700X, flashed the BIOS to 2.10, then went to install the Ryzen 5 5600X. The AMI BIOS, prompted me to reset the TPM, because I changed the processor.

    TPM is enabled by default with 2.10, according to ASRock, IIRC.

    Well I would enable AMD fTPM and Secure Boot.


    Secure Boot is on the Boot tab in the BIOS and below is AMD fTPM...

    I've enabled both. I haven't had any issues with either.

    fTPM stands for "firmware" TPM. In other words, it's TPM without requiring a (hardware) TPM module.
