Stop scrolling in a certain section of my page using GSAP ScrollTrigger

I’m trying to stop scrolling in a certain section of my page using GSAP ScrollTrigger. Specifically, I have a GTLF model that I want to display in a section called “section-four” and I need to disable scrolling while the model is visible.

I’ve tried using endTrigger but it didn’t work. Can you suggest the best way to achieve this using GSAP ScrollTrigger? I’m sharing an example of my code below:
