Hi,

it works with StaffGroup:

\score {
        \new StaffGroup \with { 
                systemStartDelimiter = #'SystemStartBrace 
                instrumentName = #"aa"}
   <<
     \new Staff = "upper" \upper
     \new Staff = "theme" \theme
     \new Staff = "lower" \lower
   >>
   
   \layout {
       \context {
        \RemoveEmptyStaffContext 
       }
       \context { 
            \Score
                \override VerticalAxisGroup #'remove-first = ##t
       }
   }
} 

HTH,
  Harm
