Hello @FabioIT,
the Node-RED image is defacto a Raspberry Pi OS. You can proceed with any general tutorial for adding the desktop environment, which you can find on the offical Raspberry Pi OS webpage.
@sjp770 For sure! You still have the full access to the Linuy system and what you need is the latest development branch of evok which is under development and use a websocket connection to evok from node-red :)
