Intel AX200 Drivers

I need to include Intel AX200 drivers in to my firmware. I found a driver, but I don't know how to put it in buildroot(to setup it in menuconfig). I need just list of steps, like "what to do"
And what is in OpenWRT-wiki tutorials? Is it folder or what?

P.s. I've started study OpenWRT a few weeks ago, so I don't really know much about it)

Be aware that ax200 is not AP capable (at least not in the 5 GHz band).
