Is it possible to bake lights for objects only?

Hello!

So I'm going to be as specific as possible. I'm making a game where the player runs left. As he runs, I spawn different prefabs with challenges inside. Here's an example of what I spawn:


As you might have noticed, the torches cast light. Since this game is for mobile (Android), I need to optimize the lighting. I've already turned off all shadows. However, the realtime point lights take about 15% of my resources (in the Profiler).

So my question is: Is it possible to bake lights for gameobject prefabs that are randomly spawned? If not, what other options do I have for optimizing my project? In case you're wondering, here's the build quality settings:



Currently, I'm getting about 19-22 FPS on a Samsung Galaxy Tab 3 7.0. While it's not unplayable, it does need a bit of improvement.
