what motherboard is used in the aurora R5 supports Intel Software Guard Extensions (SGX). With a BIOS upgrade? I want to to get this to play 4k UHD Blu-Ray.

Aurora R5 does not have SGX instructions introduced with 7th Generation Intel® Core™ processor platforms and Intel® Xeon® processor E3 v5 for data center servers. "THE  R5 uses 6th Generation Core i7-6700K "
