Hi my laptop is HP 15s-eq0007au (system board 86FD 99.36) with the Ryzen 3-3200U chipset, 4GB RAM and 256GB SSD.
The Wi-Fi adapter of this laptop Realtek RTL8723DE 802.11b/g/n which supports only 2.4Ghz Wi-Fi band. I want to upgrade the adapter to a dual band one which supports 5Ghz band too. Any help would be highly appreciated. Thank you all in advance!

Your machine has the #2 above. I highly recommend the #3 above.

You would need to add a second wifi antenna for the AX200 to work, or you would not have bluetooth, and perhaps not so good wifi reception.
That would require a lot of work to run the second antenna, if you do it right.
The only wifi card from the list you can upgrade to with a direct swap is this one, which also works with only one antenna cable...

You're very welcome.
The Intel cards would only work if your notebook already has an Intel card or the Realtek RTL8822CE wifi adapter, which also needs two antenna cables to work correctly.
The other three Realtek cards work with one antenna cable, but the RTL8821CE is the only dual band model.
