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.
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.
