Turn off LED on Amp2

I've searched and the answers I found were quite old so I'd like to ask how to turn off the Amp2 LED. The Amp2 is mounted on an RPi 3B running Bookworm/Volumio. I've got all the LEDs on the Pi itself disabled, I'd now just like to turn off the Amp one. It dims when playback is paused and is on full bright when playing, but never completely goes off. Is there a way to disable it with current sw? Thanks
