foreach($tags as $tag) {
// dpm($tag) here by uncomment you can check tag slug which you want to exclude
if($tag->slug != "yourtag"){ // replace yourtag with you required tag name
$output .= '<a href="'.get_tag_link( $tag->term_id ).'" title="' . esc_attr( sprintf( __( "View all posts tagged %s", 'tracks' ), $tag->name ) ) . '">'.$tag->name.'</a>'.$separator;

You can apply condition that if tagname is not equal to your tag then only it will be added to out put.
Thanks!
