Ignore Plugin on Certain Post Type

The plugin is working great when i pass ?amp into pages. However, I’d like to have the plugin completely ignored and run custom amp code on certain post types. I’ve tried, but it just returns a 404.

add_filter( 'amp_skip_post', 'isa_skip_posts', 10, 3 );
function isa_skip_posts( $skip, $post_id, $post ) {
	
	if (get_post_type() == "summary" ) {
        $skip = true;
    }
    return $skip;
}

I want to run the following code to call a separate template to render for a post type, but the ampforwp plugin is loading and rendering a 404 page (the 404 loads in the ampforwp amp design). Ideally, just want the plugin to not run so my code below can execute.

add_filter( 'template_include', 'amp_page_template', 99 );

function amp_page_template( $template ) {

	$the_slug = str_replace("?amp", "", $_SERVER["REQUEST_URI"]);

	$args = array(
	  'name'        => $the_slug,
	  'numberposts' => 1,
	  'post_type'	=> 'any'
	);

	$my_posts = get_posts($args);

	if( $my_posts ) :
		global $post;
		$post = $my_posts[0];
		setup_postdata( $post);

		if (strpos($_SERVER['REQUEST_URI'],'?amp') !== false) {

			if (get_post_type() == "summary" ) {
				$template = get_template_directory() .  '/template-parts/amp/amp-master.php';
			} 
			
		}
		endif;
		wp_reset_postdata();	
	return $template;
}

Any help would be greatly appreciated.
