"LED dimmer" option for CC121 please?

I bought a Steinberg CMC unit. The software includes an “LED dimmer” option in Cubase that dimly illuminates all the buttons on the hardware when it is connected to Cubase. This is great! … You know, for use in, say … a studio environment?

The CC121 is shown in marketing photos, in this mode. But there is no such option in the software. or am I missing something?

Hah, that’s an old chestnut indeed! Been discussed at length. See [FR] Adjustable minimum LEDs light intensity - Steinberg Hardware - Steinberg Forums.

I believe there to be not even a hope of this, nor indeed any other modification or improvement.
