Supposed way to transport Win11 with vTPM

Hi all,
I could not find any concrete guide on this. Please excuse if I overlooked something.
I have created a new Win11 VM on M1 with vTPM. All works fine. Now I want to use this VM on another M1 Mac.
What is the supposed way to move this VM?

I understand that TPM keys need to get moved as well. Because of much trial & error with ARM VMs I have now 16 TPM keys in my keychain. How can I identify the correct one?
How can I tell the target Parallels host, how to find the new TPM keys? I just tried moving all TPM keys to iCloud, but then the target host complains when running the new VM, that the key was not found.

I use the pro version of Parallels, if that is helpful in that matter.

Kind regards,
Steven
