I want to use defer with Scripts.Render and preload with Styles.Render

I want to use defer with Scripts.Render and preload with Styles.Render, I have used some formats but my problem is not solved.

I am sharing the formats which I have used below.

@Scripts.RenderFormat("<script src='{0}' defer></script>","~/bundles/jquery")

<script src="@(BundleTable.Bundles.ResolveBundleUrl("~/bundles/jquery"))" defer></script>
