You can get the drivers directly from Intel for the Killer network cards, and it comes with all the items including the command center.   That is what I used on my R10.
Does anyone know if the new Intel Killer 6E AX1675x AX210 M.2 2230 Bluetooth 5.2 WiFi card is compatible with the Aurora R12? I noticed it is an option with the new Aurora R13 systems.
