Typically, Dell will publish that capability on their spec. For example, in this workstation model,
on page 31, it clearly states SGX feature setting as
Table 8. Intel Software Guard Exensions
Intel SGX Enable Allows you to enable or disable Intel Software Guard Extensions.
The options are:
• Disabled (Default)Intel Software Guard Extensions
If there is no SGX setting in your server model documentation, please contact Dell support to see whether they can help you escalate to their technical team to get the right answer.
