I just tried that on my computer but it doesn't work. When I install the legacy TPM driver it does appear to be functioning but it does not. Then I do BIOS update using a USB Stick and it doesn't work. I do have Windows 10 pro and tried various things but the issue remains.

In case anyone is still having problems with this. I contacted HP directly with the problem, talked to someone at their SmartFriend service.
It turns out that between the time that I last looked at this problem a month ago and now, something must have been done in a WIndows Update because now it all seems to work fine.
I did need to go to my Device Manager and then under Security devices. A device now shows up there named "Trusted Platform Module 2.0". They got me to right click that, uninstall device, and then reboot. After reboot, it reinstalled the device automatically and everything seemed to work perfectly.
Windows-R and type TPM.MSC, it now shows "The TPM is ready for use"
Manufacturer Name: AMD, Manufacturer Version: 22.214.171.124, Specification Version: 2.0

I understand that. Exactly the problem I was having. TPM didn't show up anywhere in Device Manager. Even after I re-flashed the BIOS and verified it was enabled as described previously. No matter what I did, TPM did not show up in device manager.
Then, something happened in the last month without my intervention (I do keep up with Windows Updates). My only idea is that a Windows Update must have come out that fixed this problem. Because all of a sudden, today, TPM just showed up.
If I look at my update history, the following updates were installed for me on Oct 26, 2021:
- HP Inc. - SoftwareComponent - 1.37.2560.0
- HP Inc. - System - 1.37.2536.0
- HP Inc. - SoftwareComponent - 4.2.805.0
Maybe it was one of those? 🤷
I suggest you make sure all Windows Updates have been installed including all of the optional ones. Then, check Device Manager again.

So, after many sessions with the german HP support I have to say:
There is no solution and I think, there will be no solution.
The HP support told me, I should send my Notebook to HP, they will repair it and in the end I have to pay for everything.
Also the Windows Updates and everything didn`t fix the problem.
I can`t understand why it is so difficult to build a new BIOS version with the fix of this problem.
Of course I will not send my notebook to HP support and pay for an issue which is caused by an BIOS update from HP.
Maybe there will be an update in the future, but I think it will take a lot of time. Poor HP.

Good news guys. HP first tried to get me to send the laptop for repair. I declined because I do need it and the issue is not critical. Then, in another support case, HP confirmed that there is a BIOS problem. Now that they are aware of it, they told me they would release an update. Sit tight and wait for the fix which will likely be a new BIOS version. They did not commit to a due date for releasing the fix.
