Squeaking when turning at full lock...Normal?

[Philipgonzales3]

Just curious more than anything really as my 2019 was my first truck, I think it did it also.  So basically when the steering wheel is turned all the way in parking lots and what not the truck makes a squeaking/chirping noise.  I noticed my first time when I was getting my state inspection done (bought out of state, hence why I had to get it done myself).  The parking lot was small and when the person inspecting the truck went to park it he had to cut the wheel all the way and that is when I heard the squeak/chirping noise.   Notice it the other day in the drive through when I had to cut the wheel all the way to go through the drive through.  

 

My truck is a 2020 RST 6.2L 10-speed, it is 4x4 and it has the G80.  Is it because I have 4x4 or the G80?  It doesn't really bother me, just curious why it makes this noise and if it is normal.
