Now when everything else is powered off, you get the glowing to green dots of light in your room mocking you that you can't automatically turn off the DSP.
Tape is your best friend ... a dot of electrical to eliminate it completely or layers of scotch to dim to your liking. Since the LED sits proud of the case you might have to build up the sides with tape or cardboard. There are lots of other options besides tape to dim/hide it ... like a cut out from a plastic milk bottle or any container.
You can skip this next part ... It's just my DIY mind running in overdirve ,,,
Milk jugs are HDPE which can be molded at a reasonable temperature around 350°F. I've never tried this myself but my first go would be to preheat a small ball bearing the size of the LED to 350. Then place an inch square cut out from the milk bottle over it and give it a few minutes till it looked soft enough to mold. At that point I'd remove it from the oven and use a washer (gloves/tools highly recommended over bear fingers) to hold the sides flat. Cut flange to your liking.
