How can I hide physics?

Is there a way to make physics objects that cancels out another collider? I’m working on a part of a game that involves intricately moving platforms over a abyss. I want the abyss (a very big box collider) to act as a wall so the player can’t walk off of a platform, but I want the colliders of the platforms he walks on to cancel it out so the player’s Rigidbody won’t register the abyss’ collider at parts where there is a platform.

The short answer is No but there are multiple solutions to your problems. As @Casiell pointed out in the comments, you may do it by adding colliders with different Tags or Names (I suggest you use tags) under each platform on both sides which will do the work of the bigger collider.
