How to Switch of World Streaming when Playing Cinematic Sequence in UEFN?

Ok, so I made this Welcome Cinematic Orientation for Star Wars game, but, when playtesting, the cinematic looks terrible because world streaming is on, and the assets are loading slowly into the scene. Most times, you can not even see the entire cinematic.

How do I switch of world streaming while a cinematic sequence plays so that it does not affect the quality of the cinematic?
