I can't seem to find a clear answer online, but say when you buy a B450 Tomahawk from MSI I see it has a red l.e.d. strip on the backside. Does this come on by default or do you have to install the Mystic Lightning software to make it work? Is there something in the bios to disable it if not? Basically I don't want the l.e.d.s. I see Asus has an option in their bios to disable their backside l.e.d.s. but I can't find a clear answer online about MSI. Hopefully someone that has a B450 or X470 board can answer. Thanks!
