Trying to deque some .js from source

Try using wp_enqueue_scripts with the handle like this example in your functions.php file :

add_action( 'wp_enqueue_scripts', 'remove_scripts', 100 );
function remove_scripts() {

    wp_dequeue_script( 'original-handle' );
    wp_deregister_script( 'original-handle );

}

However, this will only work if they have been loaded correctly in using wp_enqueue_scripts. Looks like they have been hard coded in a file which isn’t best practice in WordPress.
