for anybody else attempting this, was able to create a php file plugin that- while nowhere near as good as clearify- did about 95% of what was attempting and worked with static site:
/*Removes RSD, XMLRPC, WLW, WP Generator, ShortLink and Comment Feed links*/
remove_action(‘wp_head’, ‘rsd_link’);
remove_action(‘wp_head’, ‘wlwmanifest_link’);
remove_action(‘wp_head’, ‘wp_generator’);
remove_action(‘wp_head’, ‘wp_shortlink_wp_head’);
remove_action( ‘wp_head’, ‘feed_links’, 2 );
remove_action(‘wp_head’, ‘feed_links_extra’, 3 );
remove_action(‘wp_head’,’rel_canonical’);
/*Removes prev and next article links*/
remove_action(‘wp_head’, ‘adjacent_posts_rel_link_wp_head’);
// Disable REST API link tag
remove_action(‘wp_head’, ‘rest_output_link_wp_head’, 10);
// Disable oEmbed Discovery Links
remove_action(‘wp_head’, ‘wp_oembed_add_discovery_links’, 10);
// Disable REST API link in HTTP headers
remove_action(‘template_redirect’, ‘rest_output_link_header’, 11, 0);
