No. You can generate an SVP file since it’s just in JSON format, but rendering can only be triggered via the GUI for normal users.
It’s almost certainly possible in specific cases, such as for Dreamtonics themselves for testing purposes, or for specifically licensed customers that pay extra for that functionality (like that one song generator website that uses SynthV as a backend service).
But for a typical user with the publicly available products, no, there is no CLI.
