Any more details on how to adjust the rear tailgate so it's quiet?
I finally managed to adjust the bump-stops to the right height. Now the problem is gone. Let's see if I can explain this without pictures.
You need to remove the two panels at the back interior of the trunk(now you can see the wires of taillights). Reach with your hands from inside of the trunk. It is a bit hard for the left side, and you need to pull down the liner a bit and reach further in. Then you can feel the adjustment screws for the rubber bump-stops. The screws have plastic torx covers and they are removable. If you have driver bit with right size(T50) you can use that to adjust directly without removing anything, but the torx sockets are very shallow. I don't have a torx bit that can fit, so I take off those plastic covers(They are mounted by two tiny clipps to the adjustment screws, so prepare for some damage on your finger nails). Also be extra careful not to drop them. Then the torx drivers heads are exposed and I used a hex socket wrench to turn them, and you can see the rubber bump-stops from outside turning with them.

I had to try 2/3 times to completely get rid of the noise. I may not have necessarily set the stops the same height relative to the car body as the body on both sides may not be perfectly leveled to begin with, so I may have one stop slightly higher than the other. I'm happy with that as long as the tailgate stops clunking when car leans over to either side.
Hope that is clear enough with my limited English.
