Well, I guess \addfontfeatures{Mapping=foobar} would probably work,  
just leaving a message in your log that foobar.tec could not be found!  
Not very elegant, though.

The default would be none, so you could try \addfontfeatures{Mapping=}  
and see if that allowed.

Alternatively, if you haven't used \setdefaultfeatures to specify the  
mapping as a default, you could simply reselect the font without the  
mapping option: \fontspec{Charis SIL}.
