Can I reduce polling intervals in the site settings?

I read from the setting and find:

  • polling interval
  • background polling interval
  • enable long polling
  • long polling interval

How can I stop polling using these settings?
Another question, can I reduce my server’s burden if I stop polling?

If you are looking at reducing load on the server by tweaking any of those settings it is very misguided.

Changing any of this will have no impact on your performance.
