Bing is picking all the rss feed for each post, can I disable the feed in Discourse

If there a way to confirm that the noindex appear in the feed? I ask because, I can’t even find the noindex tag in the source of the rss. For instance, I also opened this forum thread with the .rss, and in the source, I can’t find the noindex either.

Thus far, I only see the feeds in the webmaster tools, in the sitemap section under the feed grouping.

Thanks,
