Answer:First please determine which type of WiFi/Bluetooth(BT) module you can use on your motherboard. Second, if you want to use CNVi, you will need to check which generation of CNVi your motherboard supports.

Which type of WiFi/BT module is supported on your motherboard?

In general, there are 2 types of WiFi/BT modules that can be used via a Key E M.2 socket.
One type uses a regular PCIe connection (for WiFi) and USB connection (for Bluetooth) via the M.2 socket.
The other type uses CNVi, which is available on specific Intel platforms only:
