Big thanks to the op for all his replies. Have a Z71 on order and had wondered if this was doable. I'd have no issues it the drl's were separate lamps, but running the actual projector headlights at a reduced voltage I may not light.
I may or may not do it but this sounds like the only way. On the VW it's a controller setting changeable via software.
Anyhow, as far as I know my Z71 will have fog lamps, so just to add to this thread, it appears there are two switches available as mentioned. And Rock Auto does carry them.
