you are right if one wants the TPM not just for teh purpose of runnign windows 11 and don't caring for its security aspects.

If one wants it secure its a bit more work as new logic to only encrypt the TPM file but nothing else is needed.

for my use case having my host HDD's encrypted i would really just want a unsecure fake tpm to make windows 11 happy and never use it anyways, i dont need pin or face or fingerprint unlock in a VM LOL
