You'll only be able to indirectly find out whether SNMPv1 or SNMPv2 is enabled on a device, by being able to successfully scan the device via SNMP using SNMPv1/v2 credentials. Whether SNMPv1 or v2 is enabled is not a datapoint that can be retrieved currently, unfortunately.
When an asset is successfully scanned via SNMP, it will at the very least show an OID on the Summary page of the asset.
