For normal staves, this is well documented in the manual, see the 
section on
"Hiding staves".

You can find the basic steps of the solution in the mailing list 
archives. However,
it seems that some details have changed, so I include the solution here:
\layout{
 \context {
   \TabStaff
   \remove "Axis_group_engraver"
   \consists "Hara_kiri_engraver"
   \override Beam #'auto-knee-gap = #'()
  \override VerticalAxisGroup #'remove-empty = ##t
 }
}
