Hi:

 

Your notebook has a single band Realtek combination Wi-Fi/Bluetooth adapter according to the specs.

 

You wouldn't be able to upgrade the card to a dual band with BT 5.2 unless you completely disassembled the notebook including the display panel to properly run a second antenna wire and you would have to order the antenna kit.

 

The only upgrade you can do without a lot of trouble would be to install this card which works with one antenna wire, but it has the same 4.2 BT version as the card you have now, but at least you would have dual band wifi.

 

Realtek RTL8821CE 802.11 ac 1x1 Wi-Fi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.

 

The card has a maximum throughput of 433 MBPS on the 5.0 GHz Wi-Fi band with an AC router and an excellent signal.

 

Below is the link to the service manual.

If that won't work for you, then you will have to find and buy a USB Bluetooth 5.2 adapter.

 

You can find this model on eBay, or Ali Express. 

 

I see some Intel 3165 cards listed on the eBay listings, so don't buy those.

On the Ali Express listings, make sure the card has the HP Part # of 915620-001.

 

Below is the link to the service manual, where you can find the Wi-Fi card removal and replacement procedure:

You're very welcome.

 

Unfortunately, you can't upgrade to BT 5.2.

 

Not without a lot of work as I had described.
