How to remove site header from posts (Gateway theme)

Hello,

I am using the Gateway theme. I currently have a header image and title which I use on the landing page of the site. However, I would like to have this only appear on the landing page, and not have in on my post pages. I would like to use the featured image as the page header on post pages, and have a menu on the top of the post page. This is the format used by most journalism platforms, so that they can maintain a nice aesthetic on post pages and allow users to navigate through a menu on the top.

Is there any way that I can remove the home page header and title from post pages, and use the featured image as a header instead?

Thank you for your time.
