Hello! I recently published two games and was wondering how to get them to be featured on the main itch page? I update them frequently with a lot of new content and fixes, but don't get many views on updates and devlogs. I feel like being featured would help the community grow a lot. Are there any rules on how to get it?

No. Staff picks games to be featured based on various factors. Just make good-looking games and game pages, and promote them the usual way.

That said, pinging the official itch.io accounts on social media with a link to your game can also help get their attention. But you should have something to show.
