Hi Joshua,
I'm Benedict, an Independent Advisor. I'm here to help you.
Kindly try searching for BIOS update and latest Bluetooth driver as well from the manufacturer's support website. Download and install it, if any. When you successfully updated the BIOS and the Bluetooth function is still missing, try installing the drivers again and see if it will now work.
Please let me know if that works.
Regards,
Benedict P.
