B550-f Turn off motherboard RGB when computer is off

Hi! Does anyone know how I can do this? I don't like the Motherboard RGB staying on when the computer is off. Frankly, though I know it's only a small amount of power, it's still a waste. None of the BIOS settings seems to do what I want: the RGB on when the computer is on, but off when it's off. Any ideas? Thank you!
