How to import remote js file(which has attributes) in another js file

Question

I want to use leaflet API and it needs the following script tag.

<script src="https://unpkg.com/[email protected]/dist/leaflet.js"
   integrity="sha512-lInM/apFSqyy1o6s89K4iQUKg6ppXEgsVxT35HbzUupEVRh2Eu9Wdl4tHj7dZO0s1uvplcYGmt3498TtHq+log=="
   crossorigin=""></script>

Now Require and getScript allows you to add the js files that we need to include but how do i add the integrity attribute. I don't have access to html, so can we add the integrity and crossorigin attributes while we include js files with getScript or require.
