can we force win8 to use ethernet instead of wifi when available?

I have read about how Windows 8 will automatically prefer an unmetered Wifi connection over a metered cellular connection...

But we are wanting a way to force laptops that have an available Ethernet connection to use that wired connection even if a wireless network is connected (users often forget to explicitly disconnect their wifi connection, so their machine continues on using it all day even though they think they are using Ethernet).

Can this be done in Windows 8 (under Windows 7 it seemed the only way to achieve this was via the hardware driver - which not all drivers even supported)...
