Google Analytics+ with manually integrated Tracking Code

Hey guys,

as we need to add anonymizeIp to our tracking-code here in germany, I'd like to remove the automatically integrated code by Google Analytics+ and use mine (below) instead.

Is there a way to stop GA+ from outputting?

(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');

ga('create', 'UA-XXXXXXX-X', 'auto');
ga('set', 'anonymizeIp', true);
ga('send', 'pageview');
