Register Script Using Defer And Async In Yii

Hi All,
I want to register my core script "jquery" using defer or async.
Is there any way to do that in yii as I am using

<?php Yii::app()->clientScript->registerCoreScript('jquery');?>

If I have to do that manually what is the way?

Also if I publish one js file as asset then also what to do?
I am not getting those answers, Please help me.

Thanks,
Maclein
