RSS feeds can be enabled the same way you setup email for this report. As you can see in the docs you can opt RSS feed from the Manager > Searches and Reports for each saved search.
hope this helps....
I've configured say 40 different search reports which run in every 24 hours and send emails to Email Alias which has almost 40 people - meaning = 40 reports * 40 people =1600 emails every day.
So now ask is to reduce emails that are sent everyday - let's have them in RSS feed so they don't occupy space in email boxes.
Hope that makes some sense 😐 and I do not find a way to configure RSS for existing reports.
Thanks for the help man
