vSphere 8.0.x
vSphere 8 introduces the TPM Provision Policy. vTPM devices can be automatically replaced during clone or deployment
operations. This allows best practices that each VM contain a unique TPM device be followed and improves vSphere support for
Windows 11 deployment at scale. vSphere 8.0 also includes the vpxd.clone.tpmProvisionPolicy advanced setting to make the
default clone behavior for vTPMs to be replaced.
