You are correct. On the Cerbo you can use DVCC to share voltage, temperature and voltage signals from the battery monitor to the connected devices so you do not need VE Smart Networking. Tje only thing you may mis out on is synchronised charging with lead acid batteries, but if you have lithium batteries with a communicating BMS then DVCC should do this.
Do not enable VE Smart Networking at the same time as having wired connections. There are many reports of unexpected behaviour with both running.
