I found a video of the sound from another owner who seems to have the same rattle.

There’s no issues with the function of the shifter (although it feels like a cheap toy compared to my 2 other manual cars), just this annoying sound. I would rather live with it than let the dealer rip my car around, rip up the interior, and then have the sound still be there. I’ve just heard too many stories of people having to leave their car at the dealer multiple times chasing rattles only to end up with the car worse than before.
