Hello Bjones321, thanks for joining the Intel Community.
There are 2 options to disable Bluetooth /WiFi on this NUC.
1. If you have the Proset Utility, it has an ON/OFF option when pressing the right click of the mouse on top of it
2. If you only have installed the drivers, it will be necessary to disable it in device manager.
There is not option on BIOS to turn off these features.
