Motherboard manufacturers added Intel Software Guard Extensions option into BIOS only recently. It is never present in the initial BIOS release. Thus it is not easy to tell whether a mobo supports it or not unless you actually own the board with latest BIOS installed.

https://www.asus.com/Motherboards/Z170-PREMIUM Are here any owners of Z170 WS or Z170 Deluxe or Z170 Premium? Can you confirm whether the latest BIOS 3401* offers Software Guard Extensions (SGX) Enable/Disable option or not? It should be under Advanced tab probably.
I asked the official tech support, of course, but I received no answer...
