The dealership changes the belt with no prevail. I further looked into the squeaking when starting and low idil and found the noise was coming from below and not the engine bay. I’m thinking it may be the flywheel area. Considering It’s when starting it makes sense. Like mentioned before, it’s embarrassing having purchased a new truck and having this issue sucks.

Had the same problem first when starting my 2019 6.2 Sierra. Found the mouse to come back when the starter engages after starting from stopped at a light. I hate that feature too, wish there was a way to turn that feature off for good instead of hitting the button each time I drive it. Took the truck to the dealer for the squeaky belt, they did replace a belt, however the sound is still there. Hopefully they can figure this out.
