If anyone is using Windows Autopilot and getting a TPM check error on new 2025 PCs, this is a known bug that Microsoft is working on.

I came across the note from Joe Parker the other day who wrote: "If you are seeing Autopilot errors on new 2025 PCs related to TPM attestation with pre-provisioning flows, Microsoft is aware of this and is working on it."
There is a support article TPM attestation isn't working for TPMs which use high-range RSA 3072EK, in which Microsoft describes this.
