Photon thousands of scene objects

Options
Hello everyone,

I've been making a game similar to "Slither.io" but don't know the best way to generate thousands of scene objects(Pickups, Collectibles, etc). I managed to generate them with the help of PhotonNetwork.InstantiateSceneObject(). But how to Enable/Disable/Change their position randomly in the gameplay and what is the best way of doing this ?

Thanks and appreciate.
