User Customization - Graphics - Help

Hey all.
A quick question.
How can I expose the settings to the user, to adjust the reflection/global illumination modes i.e to switch between Ray Tracing and Lumen.
Also, is there a way that I can expose the “Use Hardware ray tracing for lumen when available” setting that’s inside the project setting. I want to give the user enough freedom to toggle between software RT and hardware RT and customize their desired look.

Thank you !
