Lights producing unwanted star burst when power is set too high

I just started using Blender Octane and I'm trying to convert a scene that I had done in Blender Cycles. So I started playing with the Octane native lights, and at least for the spotlight, when I set it too high and in space, in a planetary environment that has a star field, the light produces an unwanted star burst that I don't like at all. This is what I mean:
This is even if I turn off Camera Visibility in the object settings. Is there any way to get rid of that? I thought a simple Google search was going to give me answers, but that's not the case.

By default Octane has the
PostFX enabled (Bloom, Glare) which can be disabled. The documentation should cover the basics a slightly beyond.

Thanks, I figured that out watching a tutorial on YouTube.

Hey, that's interesting about the starburst effect! I've run into similar lighting challenges trying to get the right look in Blender. I wonder if playing with the light source's radius or falloff settings in Octane might help soften those harsh edges causing the starburst. Actually, reminds me of some of the graphic details in the game Drift Hunters, where lighting is critical to the visual experience, but with different end-results to be achieved. Maybe analyzing other examples could give you clues? Good luck finding a solution!
