I have some question

No. This is a 2012-vintage system; TPM 2.0 did not arrive until two years after that.

Hi

The Register is a good source of info, like this (perhaps you should register with them, I have) ...

https://www.theregister.com/2021/10/06/bypass_windows_11_requirements/

The KEY phrase is

"AllowUpgradesWithUnsupportedTPMOrCPU"

that maybe of use to you.

Microsoft sort of "approved" Microsoft's warnings are severe.

A disclaimer explains that the installation "may result in compatibility issues"

and that "your PC will no longer be supported and won't be entitled to receive updates"

– though it seems that Microsoft envisages certain scenarios

where the bypass may be a good idea,

since the heading states "not recommended unless instructed by support."

You risk invalidating any support or Warranty.
