Anyway to trigger a zwavejs2mqt NVM backup from an automation?

I’d like to setup a zwave NVM backup to backup the zwave stick monthly to a NAS. I was hoping there was some service I could call to trigger it, but doesn’t seem like it. Anyone done anything like this?

No, unless you enable MQTT. The z2m backup configuration lets you set a time-based backup anyways, you don’t need an automation.

Edit: Wow I completely missed that backup section in zwave2mqtt, awesome! So I can schedule an NVM backup which is perfect… but how do I get that backup file so I can move it to my NAS?

It gets saved in the store directory, which is a docker volume. Just backup the volume, or extract it from there. Or, manually download it from the store UI.
