Hi @Ryota,

Thanks for writing in to report this!

We are aware of some incompatibilities with certain TPM chipsets, such as Ryzen's fTPM and VMware's vTPM where the system reports back with no TPM attestation support that we need. What's really odd about these two is that when we compare it with the system tools, they are available but when we go through our APIs, they're not. Also of note, we did see available TPM support with an external TPM chip on top of Ryzen 5xxx series mobo, so it is possible to enable TPM in that setup, just not with Ryzen's fTPM (yet).

We are working with Microsoft to determine the reasoning behind it or to see if we can improve our support.

At the moment, there isn't a way around this yet that we can find (beside using the external TPM chip). Hopefully, we'll have better news in time as we continue to gather more information and work with Microsoft on this.
