Cannot check TPM discreteness using Intel BootGuard status: no TPM2 device is available

Testing with _ubuntu-25.10-snapshot3-desktop-amd64.iso_ gives me:

`sudo mokutil --sb-state [ -d /sys/firmware/efi ] && echo "UEFI" || echo "BIOS"`
`SecureBoot enabled`
`UEFI`

`sudo tpm2_getcap properties-fixed`
