Simplest Button Assigned "Action" to Turn Mouse Lights Off

Hi, I bought and hooked up the Sabre RGB mouse as well as the Strafe RGB Keyboard. The keyboard has a designated key to illuminate the keyboard background to different levels of brightness as well as turning off the light.:sillygrin This button is great for the keyboard, but there is no button like that on the mouse.:ummmm:

 

I have figured a complicated method that might work would be to use multiple profiles. I can create and maintain two profiles for the mouse, and assigning a button to switch between them.:sigh!:

 

Is there a simple way I can assign a button on my keyboard or mouse to disable the light on my mouse?:question:

I don't think the option to change the brightness/disable lighting as an assignment is available.
