Trim a layer for faster rendering- Automation blocks

I have 200+ layers, and my rendering is very slow. I want to speed up my render. How can I trim a layer for faster rendering? The layer is currently present from start to end, but I want it to be visible only during a specific time based on the animation. When a text or shape appears on the screen and then moves out, I want the layer to be trimmed accordingly.

Thanks in advance for your help!
