Completely remove next/prev links

I changed the settings within the next/previous navigation page, by specifying none for the location of the links. They are gone from display, but when I look at my source code, I still see them as "<link rel='prev', rel='next, and rel='start'...

I would like to get rid of them completely, no links within my code. How can I do this? Do I need to modify a php template, or is there a setting somewhere.

Thanks.
