Puppet users - Jul 2014 - Puppet Dashboard 1.2.23 disable link in Main html page

Can someone point me to a way to disable the Puppet Dashboard Version link 
in the top left corner of the main page?
 
Is there a possible way to do this through settings.yml file?
 
The reason I need to do this is that we have no internet access and 
clicking on the link attempts to connect to github and i'd like to avoid 
that.
 
Otherwise any way I can find the source page for the code , I would 
appreciate your help, thanks in advance.
