VBS and TPM Chip

Hi All

In the Microsoft documentation a TPM Chip is a hard requirement for VBS:

https://learn.microsoft.com/en-us/windows-hardware/design/device-experiences/oem-vbs

But VBS can be enabled without a TPM Chip. VMWare also describes this scenario:

https://blogs.vmware.com/vsphere/2018/05/introducing-support-virtualization-based-security-credential-guard-vsphere-6-7.html

I'm now wondering, if the Microsoft Article is wrong and it is an optional requirement in fact; or if the feature is only supported, if a TPM Chip is present.

As Windows Server 2025 comes with VBS enabled by default, this could be an issue (Most visualized Systems to hot have a TPM Chip by default)...
