Unknown devices in device manager

My Chuwi Hi10x was stock and there were no unknown devices or yellow exclamation marks in device manager, that was until I just had a look earlier today.
I can only conclude that the win 10 version 2004 update is the culprit… has anyone else had this problem and successfully rectified it?
I’ve tried searching for drivers automatically and via windows update and even tried manually updating using the 3rd party driver pack that @level1imp posted here but to no avail

Hey there

I am still on the original Windows that came with the tablet and I don’t have any unknown devices or hardware.

Running Windows version 20H2
Os build: 19042.546

do you have either of the following listed in device manager?
Broadcom GNSS Bus Driver - 47521

No i dont have any of those

I have the same problem too

I’m assuming NxpNfcClientDriver is NFC tech,
and the Broadcom is a GPS chip

So I managed to sort this out… I loaded the BIOS and reset/loaded the defaults then booted back into windows and these unknown devices disappeared.
I find this odd since I never changed anything in the BIOS
