   It looks like we need to be very careful about processor selection if we 
want SGX MEE and not TME. 
   I'm reading these specs as saying "if it has TME then it isn't using MEE". 
   
   Maybe there's a BIOS setting to set Ice Lake chips to use MEE with a smaller 
Enclave Page Size (ie 0.5 GB) ?  
   Xeon E series all seem to have SGX MEE.

     - Intel® Software Guard Extensions (Intel® SGX): Yes with Intel® SPS 
     - [Doesn't mention TME so must be MEE]

     - Q2'21
     - Intel® Software Guard Extensions (Intel® SGX): Yes with Intel® SPS 
     - **Intel® Total Memory Encryption: Yes** [so not MEE]
