   Enqueuing a script only if we’re seeing a single post and comments are open for the current post

   
   /**
    * Enqueue wpdocs_script if viewing a post with comments enabled.
    */
   function wpdocs_scripts(){
   	if ( is_single() && comments_open() ) {
   		// wpdocs_script must have been previously registered via wp_register_script()
   		wp_enqueue_script( 'wpdocs_script' );
   	}
   }
   add_action( 'wp_print_scripts', 'wpdocs_scripts' );
   

With this code you can always disable comments on pages, assuming your theme uses comments_open() to check if the comments are open.
Note: Comments are disabled on pages by default in 4.3+.

/**
 * Disable comments on pages.
 *
 * @param bool $open    Whether comments should be open.
 * @param int  $post_id Post ID.
 * @return bool Whether comments should be open.
 */
function wpdocs_comments_open( $open, $post_id ) {
	$post = get_post( $post_id );
	if ( 'page' == $post->post_type )
		$open = false;
	return $open;
}
add_filter( 'comments_open', 'wpdocs_comments_open', 10, 2 );

With this code you can enable comments on a post that has custom field “Allow Comments” set to 1.

This is helpful when you have told WordPress to disable comments for posts that are older than X days but wish to enable comments for a handful of old posts.

/**
 * Enable or disable comments based on custom field Allow Comments.
 *
 * @param bool $open    Whether comments should be open.
 * @param int  $post_id Post ID.
 * @return bool Whether comments should be open.
 */
function wpdocs_comments_open( $open, $post_id ) {
	$post = get_post( $post_id );
        if (get_post_meta($post->ID, 'Allow Comments', true)) {
		$open = true;
	}
	return $open;
}
add_filter( 'comments_open', 'wpdocs_comments_open', 10, 2 );

// Отключаем комментирование
add_filter( 'comments_open', '__return_false' );
