Yes, you can replace it with:

www.youtube.com###items > .ytd-watch-next-secondary-results-renderer.style-scope:nth-of-type(n+2)

This will block the 2nd item and onwards. Note, YT seems to use display:none for behaviour and will fetch up to 160 records for every page, 20items at a time.

Admittedly, I was lazy and didn't bother to play around or experiment after I had copied it. This is a nice update.
