Look at which net you're using.

Make a copy of that file from $MESA_DIR/data/net_data/nets into your
work directory.

  cp $MESA_DIR/data/net_data/nets/basic.net no_burn_h.net

Open up no_burn_h.net in a text editor.  basic.net is quite readable.
Comment out (or delete) the sections "pp chains" and "cno cycles".  The
comment character is '!'.

Then, in star_job point MESA to your new net

  change_net = .true.
  new_net_name = 'no_burn_h.net'

P.S.  Evan's suggestion is also great.
