Render Stills from Server

Hey everyone! Hope this message meets you well.

I`m currently working on a project which will use UE for stills rendering and I wonder if it’s possible to create and save those stills using only an Unreal Engine server instead of having to execute a realtime “gaming” application in a server?

In other words, is it possible to have a background application as Unreal Engine server only listening to commands and taking still images based on metadata?

Thanks for your attention!
