2014 Gen 1 (Rod Knock) Sound. Need help.

Does the sound go away when transmission is put into D or R or just when fans kick on an place load on the engine etc.
Since the fans are electric and and the sound goes away when they kick on, I would be looking at the front accessory drive as well. Weird that the noise is coming from the back of the engine.

I’d suspect a cracked flex plate. It sounds just like a rod knock.
