You can set the bike to not warn you about any low pressures, while the riding mode is set to Enduro or Enduro Pro. Check your manual... very handy feature! But, as soon as you go back to Rain/Road/Dyna mode it warns you again.
Edit: As this is posted in the LC section I assume you are referring to the GSA LC? If not (older GSA) then my statement above does not apply.
