For this, you will have to use a firewall policy with Application Control: https://community.fortinet.com/t5/FortiGate/Technical-Tip-Block-Facebook-while-allowing-Messenger/ta-p/247606

    Thanks jiahoonsg112. But it can't block the facebook messenger app, also need deep inspection. Is there any other way to block the messenger app with only ssl inspection not deep inspection ?

    Deep inspection is required for this , SSL inspection only inspect the header of the packet which might not help you to block  facebook application in this case hence the KB mention Deep inspection is required
