My F12 Berlinetta is Making a Strange Noise - Can Someone Help Me Troubleshoot?

I've been driving my F12 Berlinetta for a few years now and have never heard anything out of the ordinary, but recently I started noticing a strange grinding noise coming from the engine area while accelerating. It's not loud enough to be annoying, but it's definitely noticeable and has me worried. Anyone with experience on this model have any ideas what could be causing this?
