don't show "static sites" in RSS Feed

[ghost]

is there a possibility to stop listing "no post sites" in the rss feed?

let me give you an example based on your blog.
In your rss feed (https://adityatelange.in/index.xml) there are also sites listed like "About", "Archive" and all the other pages that are not real articles.

{{- if and (ne .Layout `search`) (ne .Layout `archives`) }}

Archive won't be present.
You can hide any post you want. Pls search docs for the front matter variable.

sorry, maybe i am blind. I can not find any informations about "front matter variable" in docs.
Can you link this information to the discussion?
