> there is now a requirement for new Windows Server hardware to include TPMs and they are automatically used by the installer.

They are required for new Windows Server *certified* hardware, that is, for hardware to be specifically blessed by Microsoft.

As I have said in the comment above:
> Microsoft has sai[d] it will require TPM and Secure Boot for the *hardware to be certified* for the next (not yet retail) version of Windows Server (2022),
> but there hasn't been any announcement that it will require these features to actually run.

Nothing in the article you mentioned says that Windows Server will run only on hardware certified by Microsoft.

That is, you can run Windows on hardware that lacks these features.
Just the hardware will not get "blessed by Microsoft" badge.
