How to disable scroll on first section?

Hello everyone,
I am working on my portfolio and I have a intro page with click interaction. I would like to disable the scroll function only on this section, after the click the view can continue scrolling down. Is it possible?(I guess so… :slight_smile: )
I could use some help on this, thanks a lot!

Kind regards
