It may be easier to look in the BIOS/UEFI and see if there's a way to
disable Bluetooth and Wifi. Then you don't have to worry about drivers
loading for chips that are no longer powered on.

I often disable Bluetooth and Wifi for machines in my house that have
a full time wired connection. There's no need to turn on all the
radios when they are not used.
