You have a few options, depending on the degree of alignment you do want 
between the staves.

%%%%
\version "2.22.0"

staffI = \new Staff \fixed c' { g4 a b a8 g | fis4 e f2 }
staffII = \new Staff \fixed c'' { c2 d4 b, | c4 d bes,2 }

zeroSpacing = \with {
  \override VerticalAxisGroup.staff-staff-spacing =
  #'((basic-distance . 0) (minimum-distance . 0)
     (padding . -inf.0) (stretchability . 0))
}

\new StaffGroup \with \zeroSpacing << \staffI \staffII >>

\markup \overlay {
  \with-color #red \score { \staffI }
  \with-color #blue \score { \staffII }
}
%%%%

The first approach above eliminates spacing by using an extremely 
negative padding to permit overlapping staves within a system.  The 
second approach uses \markup to overlap the stencils from two scores.

With the first option, there is still general time alignment between the 
systems, which if you do want measures to line up, that would be the way 
to go.  With the second, each staff is completely isolated from one 
another.  In the example above, I added color to each staff so you can 
better see the effect.
