Hi [NAME]-Jordan the Dell support documentation includes how to open laptop to remove the existing Wi-Fi adapter card and install a different Wi-Fi adapter card that includes Bluetooth. A USB Wi-Fi adapter that includes Bluetooth can be installed externally without opening laptop. Have a look at How to Add Bluetooth to Your Computer (lifewire.com). 
Is there a way to add bluetooth to my system?
