2019 limited with weird screeching at cold starts

If i had to guess its the belt? or something belt driven? Here is a couple vids with audio, this was first start in the morning at about 45 degrees weather. It goes away once the engine has been running for maybe 3 or so minutes and no longer there once at op temps as well..any guesses from the more experienced on here? Gonna call dealer tomorrow, but who knows with them, they will probably say it normal engine noise lol

Sounds like the grille shutters trying to close but failing to reach their closed position.
