Modify action buttons for custom post type

If you look here https://developer.wordpress.org/reference/hooks/post_row_actions/, the second argument for the post_row_actions filter is a post object, so you should be able to do :

 function remove_quick_edit($actions, $post)
  {
    $post_id = $post->ID;
    $post_type = $post->post_type;
    if($_GET['post_type'] == 'form-enquiry')
    {
      unset($actions['inline hide-if-no-js']);
    }

    $actions['reply'] = '<a href="#">Reply</a>';
    //return $actions;

    echo '<pre>'; print_r($actions); echo '</pre>';
  }
  add_filter('post_row_actions', 'remove_quick_edit', 10, 2);
