There is no "exec" SSI command support in nginx.

In this particular case I would recommend using if with regular
expression and echo commands instead. Something like this should
work:

<!--# if expr="$request_uri = /(?P<foo>.+)/EN/(?P<bar>.+)" -->
<a href="<!--# echo var="foo" -->/GE/<!--# echo var="bar" -->">Deutsch</a>
<!--# endif -->

(Untested.)
