1000 Rigidbodies in Unity 3D. Possible?

Hey guys, I need someone who knows how to smoothly make 1000 Rigidbodies work in Unity 3D. The game is totally physics-based and the idea is to make the player interact with them. The scene setup will be like 1K balls in a pot/pit. Already tried all possible physics settings in Project Settings ( Followed Brackeys tutorial on: How many Rigidbodies can Unity support? - YouTube). Any help would be appreciated.
