As the WP3 configuration is under development in the cnMaestro configuration, it is possible to configure WPA3 with the new Wi-Fi6 AP´s through a User-Defined Overrides script. You configure your “WLANs” as normal with WPA2 and push a script to the User-Defined Overrides section into the matching AP-Group.
See following example script and attached screenshot for WPA3-PSK:
!
wireless wlan 1
security wpa3-sae
passphrase hallo12345678test
!
