Can HP Spectre x360 laptop's TPM 1.2 be upgraded to TPM 2.0?

[MSTEGER]

I see WIN11 will require TPM 2.0 whereas my HP Spectre x360 (13-4003DX) has TPM 1.2. I see some HP laptops/notebooks can be upgraded with a firmware upgrade but I find nothing about Spectre x360 models. I ran the test from whynotwin11 and the only thing that failed in the WIN11 test was the TPM. My TPM 1.2 is running/available but not compatible with WIN11. All other hardware/software items (processor, RAM, storage, etc.) pass the compatibility test. Is there a firmware or other upgrade available for my model to upgrade from TPM 1.2 to TPM 2.0?  Thanks.

It is not a simple matter but this tutorial explains the process:

I had already found that article but when I d/w the HPIA, my machine (actually, no HP Spectre x360 models are listed) isn't listed in the long list of HP models. So, I am still not any further in doing it. It seems there was an HP Trusted Platform Module (TPM) Configuration Utility but all I can find is a dead link to this program.  I can't find a valid link to use.
