One of the things that people tend not to like about Specialized is that they will use their a lot of their own house branded parts. The "Crave SL Disc 29"" listed on the spec sheet as the rim for that bike is a good example. It might be a rim that goes tubeless reliably, or it might not. If it is...Yeah. If not, you'll waste a lot of time, money, and effort in a pursuit that will probably see you burping and crashing at what was already a very exciting part of the ride.
Your best bet is to go to the shop that sold it to you and see what they say. I would guess you're probably not the first person they've sold that rim to that has wanted to go tubeless. Kind of sucks though that you have to be a ginny pig.
Looking at the specs on the rest of the wheel....14g straight spokes, and Specialized HiLo hubs, that's not a wheel you'd want to spend a lot of time and money trying to make work.
If it were me, unless I got an "absolutely those will go tubeless, those rims are actually a re-branded XXXX (something with a good reputation for tubeless performance)" from the shop, I'd just continue to ride it with tubes and spend the next couple months hunting deals on a new wheel set or, better yet, the parts to build new wheels. Find a set of Hopes at 30% off, grab a couple of WTB Frequency or KOM rims on year end close out, and have measure the stuff, order the spokes and put it together for you. That's a much better solution.
i guess you could use a different brand. i used the stans tape though, and taped my rims then installed the two valves that come in the kit. then you start to put the tire on the rim and add the sealant then set the tire before inflating with an air compressor to set the bead fast. then spin the tire to evenly distribute the stans and you are good to go.
