Push local network access policy via a policy

Is there a way to push a policy that will allow device and apps and local netwrok access via MDM (https://support.mozilla.org/en-US/kb/control-personal-device-local-network-permissions-firefox)? We need to allow Firefox to access an app agent that is running on a device via localhost. We would like to do it with a macOS profile, Windows GPO and a json policy for linux. I can't seem to find this setting in policy templates.
