VBS and TPM Chip

Hi All

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

Virtualization-based Security (VBS) | Microsoft Learn

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

Introducing support for Virtualization Based Security and Credential Guard in vSphere 6.7 - VMware vSphere Blog

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)...
