How do I know my vim4 is wifi6 standard(802.11ax)?

VIM4
1

Hi there,
I have configured my vim4 to be hotspot in the following way:
$ sudo nmcli con add type wifi ifname wlan1 con-name Hostspot autoconnect yes ssid khadas_ap
$ sudo nmcli con modify Hostspot 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared
$ sudo nmcli con modify Hostspot wifi-sec.key-mgmt wpa-psk
$ sudo nmcli con modify Hostspot wifi-sec.psk “12345678”
$ sudo nmcli con modify Hostspot ipv4.addresses 192.168.2.20/24
$ sudo nmcli con modify Hostspot ipv4.gateway 192.168.2.1
$ sudo nmcli con up Hostspot

So, how to know if it’s wifi6 standard?
How to configure it to be wifi6(802.11ax) or others(802.11b/g/n/ac)?

Thank you
