Please review the notation reference, section 1.2 Setting automatic beam
behavior.

\set Score.BeatStructure = #'(2 2 3)


If you are going to mix your music between 7/8 and 9/8, you'll probably want
to refer to Notation Reference 1.1 Time signatures.  You'll want to use

\overrideTimeSignatureSettings
   #'(7 . 8)  % timeSignatureFraction
   #'(1 . 8)  % baseMomentFraction
   #'(2 2 3)    % beatStructure
   #'()       % beamExceptions
  

\overrideTimeSignatureSettings
   #'(9 . 8)  % timeSignatureFraction
   #'(1 . 8)  % baseMomentFraction
   #'(2 3 2 2)    % beatStructure
   #'()       % beamExceptions
  

Then, when you change the time signature to 7/8 and 9/8, you'll
automatically get the beaming you want.

HTH,
