Depending on your BIOS manufacturer and your PC configuration you may have options to disable hardware devices and I/O ports that you do not need for your audio setup. Examples include Bluetooth, the integrated camera, your card reader, a fingerprint device and a LAN.
You may also want to disable the integrated sound device on your PC since you are (hopefully) using an external audio interface.
If there are no settings in your BIOS to disable Bluetooth and other devices, refer to the next section and disable them via the Device manager in Windows.
Please check thoroughly other BIOS/UEFI settings on your PC to get to know your system, then save your changes and reboot your computer once you are done.
