Category and keyword page – layout same as blog page layout?

Hello,
I’m trying to get information about a change of the result page for the category page and keyword page.

So far, I only fount this code:

function change_blog_archive_style() {
	global $avia_config;
	if(!is_single()){ $avia_config['blog_content'] = "excerpt_read_more"; }
}
add_action('get_header', 'change_blog_archive_style');

This changes the layout already in a better way, but I would like to achieve the same layout as I set for the blog in the backend.
My blog has a grid layout with the featured image, the title, an excerpt and a read more link.
Then I also deselected some features as date, author and so on, but the category page still shows all this information.

How can I get this done?

Thanks for help,
Enrico
