Drove 200 miles today just to be able to try this. No luck getting the option to be available in the IPC (yet), but changing 726-49-01 did the magic. The checkmark is gone. I am unable to physically verify they are in fact off, because my truck doesn't have any headlights. But I consider that a good sign.

So are you saying you changed 726-49-01 from 0101 0101 01 to 0101 0101 00?
I can't tell from your picture. Is the 'Daytime Lights' still grayed out as in you can't select and unselect it?
