Good afternoon.

In most cases, the chirp comes from either the serpentine belt or the tension-er.
Take a spray bottle and spray the serpentine belt and see if the noise goes away.

Also, if I may jump in here, you can visually inspect the belt. Here is a guide on what to look for: https://www.2carpros.com/articles/how-a-serpentine-belt-works
