Can the AOA donut brightness be adjusted?

Flying at night I dim the MFDs, the HUD, the backround illumination, etc. But the donut is full bright and really annoying. The engine and fuel level panel is similar. Although there is an adjustment knob for it, the knob does little to nothing.

There is a brightness knob on the lower part of the UFC, labeled AOA, under the HUD brightness knob.

For the second part, to he cockpit lighting must be in night to adjust IFEI brightness. (This will also make IFEI text green)

Switch is in the lighting controls outboard of the right console.

Thanks guys. A funny aside. The very next thread I clicked on (What is S mode?) has a pic where I can just see the AOA knob.
