To enable acccess-based enumeration (ABE) on a netapp share we need the commandline. Just connect with putty or something else to your netapp where the share resides.
To set ABE to on, use the nest command:
cifs shares -change sharename -accessbasedenum
To turn ABE off, use the command:
cifs shares -change sharename -noaccessbasedenum
Like Christoph says in the comments you can enable ABE from the commandline tool abecdm.exe just from a windows server, so you don’t need the commandline from a Netapp.
If you do not have this tool you can download it here:
