Siteimprove script in source code

When activating this module and adding ID the siteimprove code appears in html source code as script tag.

<script>(function() {var sz = document.createElement('script');
      sz.type = 'text/javascript'; sz.async = true;
      sz.src = 'https://siteimproveanalytics.com/js/siteanalyze_XXX.js';
      var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(sz, s);
      })();
</script>

Because of this 'unsafe inline' tag has to be used for CSP rules.

Would it be possible to make this in <script src=""></script> file?
