Try it and see. "Daytime lights" (DRLs) are the headlights. What you're calling DRLs are the tri-bar lights which will stay on regardless of the headlight setting.
Should do what you want. I have that unchecked so my low beams are not on all the time. I keep lights on auto and everything works as i expect it to. I wish i could turn off the tri-bar lights as easily. If you can do that with Forscan, then that will happen at warranty's end.
