By hand, you will need to set the option after including Galaxy.inc and
before including Galaxy.bg (assuming you want to use Galaxy.inc to set some
random options - if not, you can skip it altogether and declare your desired
options before including Galaxy.bg), e.g.:

   #declare galaxy_seed = 12932;
   #declare options_only = true;
   #include "galaxy"

   #declare galaxy_bgnebula = false;
   #declare galaxy_nebula_sphere = false;
   #include "galaxy.bg"
