Though not supported by specialized, your best option is to probably setup your wheels tubeless with tire sealant. Keep an extra bottle of sealant with you just in case you have trouble on the trail and need a refresh, but keep a tube handy if that fails as well.
Some folks have had good luck by injecting some tube sealant (like slime) inside their inner tubes as a preventative measure as well. You might get a few punctures, but they can seal up with this method. You'll probably want to have a pump handy as you may still loose a bit of air from time to time. Some folks have had good luck using tubeless sealant in place of tube sealant, but YMMV.
I've also read a some discussions about possibly building your own tire liners from several layers of TYVEK shipping envelopes taped together, but have not really heard much talk to how effective that is in practice.
