Turn lights off on shutdown with Armory Crate

I have been using Aura with my ROG 1080ti and z270 mobo, but I recently upgraded to a 3070 KO and have been forced to install Armory Crate to control the RGB on my graphics card.

The problem I'm having now is that when my PC is powered off, the motherboard RGB strip displays a rainbow effect. I cant seem to find anywhere to disable this with Armory Crate. Does anyone know where this setting is located, if it exists? TIA.
