Processor support is not enough to have a fully Intel SGX–enabled system.
Four conditions must be met for Intel SGX to be enabled on a system:
Contact the motherboard vendor or original equipment manufacturer (OEM) for guidance on exposure and location of Intel® Software Guard Extensions (Intel® SGX) settings in the BIOS.
It is the responsibility of the BIOS manufacturer to expose Intel® Software Guard Extensions (Intel® SGX) settings in the BIOS.
Refer to Properly Detecting Intel® Software Guard Extensions (Intel® SGX) in Your Applications for a full explanation of detecting and enabling Intel SGX on a platform using Intel SGX Software Development Kit commands.
