Hello,

Try below code on On-load client Script for duration field to hide hours, min and sec:

function onLoad() 
{
 document.getElementsByClassName('col-xs-7 col-sm-12 col-md-12 col-lg-8 no-left-padding-lg')[0].style.display='none';
}

Let me know the result.

If you noticed in below code there is an array index number which will specify the index of duration field. In case of multiple duration field you need to specify the index number.

document.getElementsByClassName('col-xs-7 col-sm-12 col-md-12 col-lg-8 no-left-padding-lg')[0].style.display='none';
