we can add

\unprotect

\def\v!sansnormal {sansnormal}
%def\v!sansbold   {sansbold}
\def\v!serifnormal{serifnormal}
\def\v!serifbold  {serifbold}

\definealternativestyle [\v!sansnormal]  [\ss\tf]
%definealternativestyle [\v!sansbold]    [\ss\bf]
\definealternativestyle [\v!serifnormal] [\rm\tf]
\definealternativestyle [\v!serifbold]   [\rm\bf]

\protect

\setupmathematics[functionstyle=sansbold,functioncolor=darkblue]
