open up your phone (check youtube on how to do that) and put some soft 1 millimeter thick sticky electrical tape on top of the round vibrating motor on the right side besides the USB-C connector.
I used this tape: https://www.amazon.de/gp/product/B01DUI4CF2/ref=oh_aui_search_asin_title?ie=UTF8&psc=1 It is 0,75mm thick self sealing electrical tape that is sticky on both sides.
The problem seems to be that the metal housing of the motor needs to be isolated from the metal back plate of the phone. metal on metal = rattling noise. No need to pull any cables. I left the fingerprint reader connection on while doing this fix.
Don't put to much tape on it though because it hardens with too much pressure on the back plate of the phone and the isolating properties are gone (rattles again)
Hope this helps someone who is looking for a solution for this. I could not find any real fix for this. The rattling noise was driving me nuts.
