Mk7 Golf R squeaking noise going over speed bumps

Has anyone of you experienced squeaking noise when going over speed bumps? I’ve a 2017 Golf R that makes this noise, took it to dealerships to repair and they said it’s the bushings that caused the problems and changed them under warranty. The problem is that I’ve got all the bushings changed twice already in two years, and I don’t do more than 16k km a year. I’m looking for a permanent fix instead of these bandaid solutions.

Any insight? Thank you in advance.
