My HP computer is currently on Windows 10 Pro and could not update to Windows 11 on my HP Pavilion 27-xa0045z All-in-One PC - AMD Ryzen 7 2800H 3.35GH.
It displays a message indicating that my computer which I bought in May 2020 as indicated above does not meet the minimum requirements for upgrade to Windows 11. I have been trying this upgrade since Windows 11 came on the market and still have the same problem despite my TPM being enabled.

The only thing I can think of that is causing that problem is your PC has a firmware based (fTPM) 2.0 security device which for some reason W11 does not recognize as a hardware based TPM 2.0 device.
I've seen that on the HP 15-ec0xxx model series which also has an AMD processor and comes with a fTPM device.
A TPM 2.0 device would show up in the device manager under a Security Devices category.
Your device manager's Security devices category probably only shows an AMD PSP device, but it would show both devices if the fTPM 2.0 device was a hardware based TPM 2.0 device.
Until Microsoft fixes W11 so that it recognizes a fTPM 2.0 as a TPM 2.0, the only way you will be able to upgrade to W11 would be to use a workaround to bypass the W11 hardware checks.
If you are interested in doing that, you can read this discussion at the link below for how I upgraded several desktop and notebook PC's to W11 that did not meet the hardware requirements.
