If it was the brakes, and it could be a harmless brake squeal, the noise would change or go away if you ride the brakes a little while maintaining speed. So not likely brakes.
If it’s not rpm sensitive then not likely to be the accessories or belt.
It’s not random, it’s rotational, so can likely rule out odd non moving parts squeaks as suggested it may be.
If I read your dash right, 111k miles. If it’s on original u joints or carrier bearing then those are the likely culprits. U joints can dry out and if very mild/shallow driveline angles (like a long RV) the u joints dont exercise much and can go a long time before actually showing other signs of pending failure.
After 100k miles u joints and carrier bearings are nearing the end of their service life, frequently.
But you have to get under it and diagnose. Any grease splatter or rusty dust around u joint cups is a sure diagnosis. Any slop in carrier bearing or torn rubber is as well.
