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.

If you do not want Bluetooth to run you can simply disable it in systemd.
sudo systemctl stop bluetooth.service
sudo systemctl disable bluetooth.service
