Is this noise normal?

We had a new Trane XV18 installed in 2021 and the defrost has cycle has squeeled on this unit ever since. The dealer says the defrost cycle is noisy but I don’t understand the squeeling noise. Has anyone else experienced this.

    If you had over 550 psi of head pressure, you'd squeal too.
    That is pretty annoying. Can't say to whether or not that's "normal" for that unit. But it's not my definition of normal. Does the original installer still service it?
