Dell Vostro 3520 WiFi Card Replacement

Hello,

I've recently purchased Dell Vostro 3520 with i5-1235U CPU.
Unfortunately, it was shipped with very old WiFi AC 9462 card - it's 1x1 and giving really low speeds especially for 2.4 ghz channel.

Now I want to replace this card with WiFi 6 card. Specifically, I need to know whether the motherboard in this laptop is cnvio2 enabled or not (as CPU is 12 gen  - and so it probably is) and whetner I can install one of the following Intel WiFi cards instead of current one - Intel AX201/211. 

The key question here is how to know a motherboard model to see whether it's cnvio2 or just cnvio. I don't want to disassemble the unit as I've just purchased it and going to return if the WiFi 6 replacement is not possible.

I tried to call a local Dell Support but even they failed to clarify whether those Inter WiFi cards fit or not.

Please help.

Thanks in advance.
