Documentation for the feature on Equinix Metal is in these places:

https://metal.equinix.com/product/features/

and a blog referencing SGX is here

https://metal.equinix.com/blog/power-of-three/

I will check also with docs to see what externally facing + internally facing information we share about SGX.
