I also have the same board.

It's a firmware TPM built into all Ryzen processors. Sadly, there is an ACPI based bug which causes the wrong IO memory location to be provided to the Linux kernel. I have an (exceptionally dirty) patch which gets it working, but it looks like the patch I built that from will never make it upstream. Work on it has been stalled for nearly a year.
