It would be very useful to be able to expose the vTPM to Linux guest VMs from an Apple Silicon Parallels host. There are use cases for this functionality such as officially signing kernel modules and firmware, storing ssh keys etc. Currently on 17.1.4 the option to add vTPM is hidden if type of VM is set to Linux. It appears if type of VM is set to windows and can be added and remains if the type is set back to linux. If the vTPM is added secure boot gets switched on. Regardless of what I do the TPM is not visible to Linux the kernel doesn't detect at boot and sets tpm bypass. So I can get to the point where secureboot is on but it's not possible to use the vTPM under a linux VM.
