Can SGX enclaves run at VMX root mode (or VMM)?

Hello,

Is it possible to run SGX enclaves at VMX root ring 3? As we know, Intel VMX root mode has ring0-3, so can we run a SGX enclave at VMX-root mode's ring3 and install the Intel SGX Driver at VMX-root mode's ring0?

 

That is, Can we run SGX enclaves correctly inside the VMM (or Hypervisor)

This question is inspired by one statement in the Intel SDM file: "Intel SGX functionality (including SGX1 and SGX2) can be made available to software running in either VMX root operation or VMX non-root operation", but there seems no additional description about running SGX enclave in VMX root mode.

Thanks.
