Virtualbox TPM vs hosts TPM

Question: is the TPM option in virtualbox 7 an emulator?

I want my guest OS to have NO access to the hosts hardware TPM, but instead to use a “portable” TPM from vbox, so that copying the guest to another host will bring the TPM with it.

Can i somehow identify the TPM being used by a system? (Linux guest & host) How to make sure, my guest is not accessing the hardware TPM?
