All drivers have their V/A output, so you always could power up some chains of LEDs on them, just need to do some math and that is super easy. I think btw that Telos is a lights for a life time, just need to change LED modules time from time and maybe driver in like 10 years. This is superb variant of lights, cant imagine better and more rigid option for constant use, honestly.
What about turning off some modules - no way to do this with original Telos, need to rewire it and use few relays together with other driver, no other way i see possible for this without messing something up really quickly. But there is another easier way - to have second small box with some weak lights in it, for first week or two
