It's surprising how many "non-tubeless" rims will work fine if you tape them up good and install a tubeless stem.
Also, I use the Stan's Race stuff... "now with twice the nanites!" I redo mine every spring, ride all season, and the next spring they're still holding air. That applies to my kids that are in competitive leagues, mine, my wife's bike, etc.. Some of the guys i know that use the cheap brands have to do it 2 or 3 times in a year.
As for stems, I like E13 tubeless stems, just because their cap is an integrated core remover. But Stan's stems have always worked well for me too.

Most fat bikes are Schrader, so it's really not a big deal. Stan's makes Schrader tubeless stems. If I were in your shoes, I'd measure the inside width of your rim, order some tape, a pair of Schrader tubeless stems, and some Stan's race sealant, and spend an hour on what you have.
