Does making things uncollidable and untouchable optimizes your game?

Hello! I remember that someone said that if parts can not collide they like optimize your game. Is that true? Also you can write here ways to optimize the game. I will read all replies, thank you.

I have personally used it, and I did notice a slight improvement in performance (can be observed better on low-end devices.)
