Perfectly right, and correctly documented:
"Starting from 6.4.0, the scan mode option is no longer available for flow-based AV.
This means that AV no longer exclusively uses the default or legacy scan modes when handling traffic on flow-based firewall policies."
Basically, there is only flow- and proxy- mode, making everything more simple.
