A possible definition:

#(define-public (mus:set context property val)
  (make-music 'ContextSpeccedMusic
    'context-type context
    'element (make-music 'PropertySet
               'symbol property
               'value val)))

\score {
    \notes {
        c4
        #(ly:export (mus:set 'Score 'repeatCommands '((volta "93") end-repeat)))
        c4 c4
        #(ly:export (mus:set 'Score 'repeatCommands '((volta #f))))
        c4 c4 
    }
}
