Hello,
You can seperate them with User and Policy Groups or different content filter settings of course. But the important question is what do you want to do spesifically. Do you want to use different Spam&Malware policies or different content policies or different Scanner settings ?
But if you're thinking like totally different policies and settings for each scanner, no you cannot do. The main purpose of using a Control Center is applying configurations and checking logs from one place. So,all scanners under one control center is getting same configuration except Scanner settings.
