The general answer is to add translate="no" to the html tag of your page, but that requires a code change.
So the Moodle html-page starts with (source https://stackoverflow.com/questions/12238396/how-to-disable-google-translate-from-html-in-chrome)

There are more options in the source discussion that are finer to control.

In moodle/admin/settings.php?section=additionalhtml, you can add in the section

<meta name="google" content="notranslate" />

and that should stop Google chrome to translate...
