The paid way to do this is is to buy something like Streamfab to download the stream directly from the source. Note for the most part you will be limited to 720p/1080p. Another paid software that used to be around was Redfox AnyStream but they went offline last year.
Only private trackers / scene would know about 2160p / 4K downloads and they’re not going to share publicly about their methods.
The free method is to attempt to do the video capture yourself (see earlier comments) rather than download the stream itself.
Of course for the most part tons of content has already been downloaded by others and made available via torrents, DDL, etc.
