By default, DITA2Go creates a link for each reference to a Jump footnote (see §30.9.1 Configuring and placing footnotes).
To eliminate links to footnotes:
[HTMLOptions] ; NoFootnoteLinks = No (default) or Yes (eliminate links to footnotes) NoFootnoteLinks = Yes
When NoFootnoteLinks=Yes and Footnotes=Jump (see §30.9.1 Configuring and placing footnotes), footnotes appear where and how specified, but references to them do not contain active links.
