how to move wp_enqueue_scripts in front of ?

a plugin wp_enqueue_scripts function adds 2 JS scripts in my header between meta title and description …
How can I move them directly in front of </head> or if possible into footer?

protected function enqueue_js($slug, $file, $ver = false, $prerequisite=false, $params=false, $footer = false, $json = false)
{
if(is_array($params) && $json)
{
?>
<script type=”text/javascript”>
var <?php echo str_replace(‘-‘,’_’,$this->id).’_’.$slug; ?> = <?php echo json_encode( $params ); ?>;
</script>
<?php
}
wp_enqueue_script($this->id.($slug?(‘_’.$slug):”), $file, is_array($prerequisite)?$prerequisite:array(‘jquery’), $ver ? $ver : $this->ver, $footer);

if(is_array($params) && !$json)
wp_localize_script($this->id.($slug?(‘_’.$slug):”), str_replace(‘-‘,’_’,$this->id).’_’.$slug, $params);
}
