Adjusting lighting via console commands

Is there any way to weaken or even turn off ambient lighting via console commands? I’m guessing no but I figured it couldn’t hurt to ask. It would make scene building more efficient; not having to either shoot pictures in non chronological order or to load a new map and replace props every time.

Try messing with HDR and its exposure / bloomscale via ent_fire console command, otherwise mat_fullbright 1/0
