FEAM

Good point but I couldn't found any entry for disabling the onboard device in BIOS. There are just two entries for the two onboard LAN (Intel and Killer) and I don't believe that one of them is combined with the Wifi and BT.

Hey guys, I'm still looking for a solution for my GA-Z270X-Gaming 8 onboard bluetooth/wifi device. It's a QCA61x4 (0x0CF3, 0xE300). I don't need wifi at all, but bluetooth would be very nice. I tried to bypass the onboard device by using a USB Bluetooth dongle, but macOS tries always to use the onboard device first. Any suggestions or solutions on this? Thanks in advance.
