Disabling Auto headlights
I did a search on this but I only found non-GXP and dated info related to the Twilight Sentinel feature. However, per our manual, the Twilight Sentinel feature only is responsible for the lights after we shut the car off and exit. It mentions nothing of controlling the lights while driving. I know that the Twilight Sentinel did this on other GM vehicles.
Is there any fuse or relay that isn't in the manual that I can pull? I know another option like I did on my 2500HD with this feature was to pop out the light sensor in the dash and plug it with a resistor tricking the system into thinking ambient light was sufficient. But I don't know how difficult it is to remove that sensor in the dash.

Temp solution - If you pull fuse 30 it will disable the DRLs. You can then turn your headlamp switch to half stop and only your parking lights come on, fogs and parking if you click the fog switch. This gives you more, but not total, control over your lighting choices.
I too would be interested in how to totally disable the auto lights system.
Note: I am not advocating disabling DRLs. It is a personal choice.

I've removed fuse 30 along with the relay for good measure. I HATE DRL'* and remove them on every vehicle I own.
Don't confuse the DRL'* with the auto headlights though.

DRL'* are not federally mandated.

Something I read in the past. Enjoy.
In the USA, DRLs are not required items of safety equipment. Therefore,
it *is* legally permissible for a dealer or other professional auto
technician to remove, disable and/or deactivate the DRLs. This is in
contrast with required items of safety equipment (such as airbags) which
professional auto technicians--including dealers--are legally forbidden to
remove, disable and/or deactivate in the absence of an individual
per-vehicle permission letter from NHTSA. Federal Motor Vehicle Safety
Standards apply only to those in the business of manufacturing, importing
and/or introducing for sale new motor vehicles, NOT to motor vehicle
owners. Hence, motor vehicle owners are legally free to modify, remove,
deactivate and/or disable any items of motor vehicle safety equipment
*SUBJECT TO LOCAL (STATE) LAWS*. There are no state laws regarding DRLs,
because the Federal permit-but-not-require statute supersedes any existing
state regulations banning or requiring them. Therefore, you are free to
do as you wish with the DRLs. It is not legal for a technician (and it is
not nice for you) to modify the DRLs such that they operate outside the
performance requirements of FMVSS108 (for instance, by wiring the high
beam headlamps to be on at full intensity as DRLs, which would also run
afoul of state requirements that high beam headlamps not be used in
traffic).

My gut feeling is, that if you're in an accident, after insurance has settled everything, any lawsuits you have outstanding won't be over DRL'* not being. That should be the least of your worries.

OK, I went and looked it up what I did to my Silverado and now it'* just the matter of a trip to Radio Shack.
You need a 1.5Kohm 1/2 watt resistor.
Remove the ambient light sensor from the dash. It looks like ours comes out, no major dash removal needed. Install said resistor in plug. Reinstall sensor in dash and call it a day.
