We could have told you that. Or you could have found it in the source.

We can't go and support all diff programs out there. We currently
use diff compatible cmdline arguments. If you want to use a different
tool you need a wrapper to extract the arguments and pass those to
'exam-diff'.

You don't. There is no such option.
