New guy Light question

[OutThere-Tundra]

New guy here, got my first question. Just purchased my 10 Tundra double cab 4x4. It will be a daily driver and work vehicle more than a toy. I bought it and had installed a Fisher 7.6 snow plow.

Question, I have tried all combinations on the light stalk and is there a way I can keep all outside lights off. That is to include heads, tails sides and DRLS. I plow snow on my own property only and as a plow uses electric power very heavily I do not need lights (DRLs) on in daytime operation. ( I rarely if ever plow after dark) With the plow I have double of all front lights to use power!
I use minimal heater/defroster settings either as a plow is a very heavy power user especially in real cold weather! (5-10 degrees)

I want to keep off all lights like I could with my last 2 GMs. I do not have user programmable features as this truck did not come with that package, but reading the manual know a dealer can change a lot of stuff

So say you Tundra people what can I do, or have done.

Thanks , Dave from upstate NY
