For a whole Zone, you can disable the firewall management. By disabling the option, firewall stops managing the APs of that Zone, and considers those APs as other network devices.
To change a firewall-managed Zone to a WNM-managed Zone
Navigate to Objects > Match Objects > Zones.
Select the Zone Subject and go to Settings.
On the Zone Settings page, click on the Wireless tab.
Enable the option, Disable SonicPoint/SonicWave management option.
