In re-reading, I realized you didn't get a clear answer.

We are merging the changes to Graphene to run a patched 5.7 kernel with 
these patches, so it should work for you (or anyone else) once all of 
the changes are merged.  I'd be happy to talk, perhaps off this thread, 
about how we can help you with any other SGX-related kernel testing in 
the future, or issues with running Graphene.
