How to get information about a playlist without uploading it to yt-dlp?

Question

YouTube

I can get the information I need, but either downloads the entire playlist, which is very long.
I tried to play with the download parameter, but it did not give any result at all, for example: and Does not change the download in any way. Perhaps I'm missing something else? Or does it only load information like this?
info = ydl.extract_info(url, download=False)
info = ydl.extract_info(url, download=True)
