In my experience there isn=E2=80=99t much hardware that supports Flexible Launch Control (FLC). The Intel blog post from 2018 that announces FLC lists two NUCs (NUC7CJYH and NUC7PJYH) and the Xeon E processors.[1] The feature also requires BIOS enablement so you might have to confirm with an OEM. Last time I researched this in July 2020, Dell and Supermicro had single-processor platforms that claimed to support it, but I never followed through with actual hardware. My apologies if you got this message twice, had an email client issue. [1]: https://software.intel.com/content/www/us/en/develop/blogs/an-update-o= n-3rd-party-attestation.html
