Your laptop does not have a whitelist. See p. 61 of the Manual here:

 

Manual 

 

The problem with your proposed upgrade is that the wireless card you have likely only has a single antenna. In other words, only one antenna wire is built into the system. This severely limits upgrade options. If you are serious about pursuing, we can help but it is not going to be easy. A usb wireless card is simple and cheap and will hold you over until you replace the laptop.

Do not buy wifi cards at aliexpress - most of them come from refurbishing. I.e. a laptop comes with malfunctioning wifi, they replace the module as official service from HP/DELL/Lenovo/Etc... but do not dispose of the bad module - all that crapware goes to Ali for extra profit. Sometimes it even gets to Amazon-Japan and Rakuten, not to "Prime-store" of course.

 

There is a systematic problem with Intel Wifi/Bt cards starting from the year 2015 maybe  - every 4th laptop has malfunctioning (disconnecting, self-resetting) wifi, and it can be fixed only by replacing. The frequency of such disconnects determines threshold of "malfunctioning", but I am not sure there is even one 100% stable module in the world. It looks like for Intel it is more profitable shipping tons of cheap crap than a few high-quality RF modules.... but anyway.

Buy an official Intel kit from Intel (or any manufacturer), so you get a real warranty and a chance to replace, if you got a crappy sample.

just look for compatible socket type, then for exactly the same antenna connector placement (do not damage that micro-coax coming to the board by stretching and bending)

and eventually you can find that your board model is the only available. Sometimes (it was like this 10-15 years ago) you can sacrifice BT for getting better WIFI.

And beware, upgrading to 5GHz board requires 5GHz antenna....so you need the one initially in your laptop. Or the RF reflection from unmatched antenna can kill your module, or at least make 5GHz band inaccessible.
