How do I remove the HUD (indicators, interface)?

Hello! I encountered the same problem; I don't know how to hide interface elements when the camera flies over the city, so that only the city remains visible without text and icons. I tried to modify the files and searched for commands for the console, but nothing helped. How is this done? I found an example on YouTube: https://www.youtube.com/watch?v=80b9pHebRMY&t=813s, but I couldn't replicate it myself. Can anyone help?
