The way godot handles renderers, you can't just "export it using other renderer" the project itself is built on a selected renderer at the start. Edit: Although there are a few work arounds such as launching the game using opengl with command line.
Yeah, sorry for the slight misinformation. I looked through some of the settings and noticed you can change the renderer in the projects menu (not during export from what I've seen, unless using web/mobile exports). But like you said, this may cause some features not to work.
