Not that I know (and the code doesn't look as if it does).
One could perhaps change the default language DFLT, but this will
disable the fallback to DFLT for fonts which don't know a language
and I have some doubts this is a good idea.
Imho the best way to change/set the language is to use
\addfontfeatures *and* defaultfontsfeatures (and hope that the user
doesn't use a \defaultfontfeatures afterwards):
\documentclass{article}
\usepackage{fontspec}
\defaultfontfeatures{Color=FF0000}
\setmainfont{lmroman10-regular.otf}
\begin{document}
123 test fi
\ExplSyntaxOn
\expandafter\defaultfontfeatures\expandafter{\g_fontspec_default_fontopts_tl,Language=Turkish}
\ExplSyntaxOff
\addfontfeatures{Language=Turkish,Numbers=OldStyle,Color=CCCCCC}
123 test fi
\fontspec{lmroman10-regular.otf}
123 test fi
\end{document}
