starting with macOS High Sierra 10.13.2 there will be native support for Aquantia AQtion based 10GbE network cards.
digging around in the latest developer beta of 10.13.2 revealed a KEXT named "AppleEthernetAquantiaAqtion.kext".
path to the KEXT...
got my intel NUC yesterday (the one with LAN connector but NO Thunderbolt) and everything seems to work. didn't try audio through HDMI yet. AirPlay works fine though. it won't work unless the graphics memory in the BIOS is set to 128MB, very important!
