"Standard hardware security not supported" on ASRock B550M Pro4 / Ryzen 5 3600 / Windows 10

I'm getting ready to upgrade to Windows 11 once it is available.  I know that I need to have a TPM 2.0 available for this upgrade.

I have a home-built, 6 months old desktop using ASRock B550M Pro4 motherboard (p1.20 UEFI BIOS driver) with a Ryzen 5 3600 6-Core processor and running Windows 10 Home (OS Build 19043.1288).

I have enabled SecureBoot (a single GPT-formatted SSD 1TB disk) and fTPM in UEFI BIOS.  AMD PSP 11.0 Device ("Start Menu/Device Manager/Security Devices") is working properly with driver version from 6/11/2021.

I'm stumped because I should see an enabled Security Processor in
"Start Menu/Settings/Update & Security/Windows Security/Device Security".  Instead, I see a "Standard hardware security not supported" message.

At this point I have no idea what else to try.  Any suggestions?
