I just bought the drop akatsuki indigo keyboard and it's perfect when the LED's aren't on. I have tried everything to turn off the LEDs but I couldn't. Does the keyboard not support turning off the LED or what?

I have drop alt v1 and I replaced the aluminum case with the drop alt ceramic case, however the problem is now i cannot see the rgb even with the diffuser. I can slightly see it on the north side of the diffuser but not the sides nor the southside. Please help.
