I took the time to dig through the Intel Tool Kit and see what BIOS options are hidden and or custom options. I was able to find a lot of options on waking the NUC based on date and time. I am not sure why these options are hidden in BIOS as these options are quite useful.
I did not find any hidden or extra performance options and all of the other configurable options are available in BIOS.
The ITK is available from Intel downloads under each NUC model or you can get it directly from here.
This version of ITK seems to only work on the Intel BIOS, There is a complete list of Intel boards along with each revision available. I did try it on the Rampage V Extreme BIOS and it would not open that BIOS.
