It's sufficient to copy-paste the code into your document. Note that
the redefined code has do precede \setupalign.

\unprotect
\unexpanded\def\nohyphens
  {\ifx\dohyphens\relax
     \unexpanded\edef\dohyphens
       {\hyphenminoffset\the\hyphenminoffset\relax
        \lang_basics_synchronize_min_max}%
   \fi
   \hyphenminoffset\plusthousand
   \lang_basics_synchronize_min_max}
\protect

\setupalign
  [nothyphenated]
