windows 11 tpm device not found

   Hello,  so TPM is very new for me,  and I'm stuck,  IK want to upgrade to windows 11 before they start charging for it.
I have a b550m Pro 4 mobo.
I've done all changes needed in the bios but the pc health check is telling me that the TPM module is not found?
I have enabled the tpm for amd cpus and disabled csm as well as enabled secure boot.
Do I need to buy that separately?  is there a setting that I am missing?
Any help would be greatly appreciated.
Thank you.

	I think you have to set at least two things correctly for fTPM (firmwareTPM) to work. One is in Advanced -> CPU Configuration -> fTPM Switch. The other is Advanced -> Trusted Computing -> Security Device Support. I think you might have to enable fTPM, reboot, and pick that fTPM device as the security device, or something like that, because the idea is to let you pick a hardware TPM module or fTPM as your security device. Things might be slightly different for different motherboards, etc.
