Default Rattle at idle

My new-to-me 2015 Turbo S has a rattle idling in park … this reminds me of gears that used to chatter on my 993 when the clutch was disengaged. Rattles largely seem to stop if I put the car in D with my foot on the brake.

I don’t recall this from my previous 991s … but none were AWD either. Only noticed because I was waiting with the car idling in park (freezing out).

Normal?

Does the rattle go away after raving a bit on idle? Most likely had motor mounts

I had a rattle on my 996, it was the exhaust heat shields.

Thanks. Either could be a reason, but it would not be clear to me why it would rattle at idle in park, but not (or as much) at idle in drive with the brakes applied?
