I need to know what you are referring to by "it" not supporting.
The system does support Wi-Fi 6, just not Wi-Fi 6e. It can get confusing because the "e" designates the 6 GHz band and without the "e", only the 2.4 and 5.0 GHz bands are supported. You would need an AX210 Wi-Fi card in order to see the higher frequency. Make sure and verify in the Device Manager you do actually have the AX200.
I will tell you this, those cards can be changed out but it is not easy and I would not suggest trying.
