Learn to ollie a skateboard.
Everyone who can ollie a skateboard is better at ollieing their snowboards than people who can't.
Ever watch someone mimic an ollie on a sk8, their first try? It looks terrible. This is because the mechanics are not simply intuitive and require practice, finesse, accuracy, power and timing. If you are entering this on snow without experience, you are effectively going at it blind, not that it cannot be done, but your mind and body are not going to wrap themselves around the concept properly if you just cruise around on your snowboard wondering why it doesn't "snap" "pop" "are my legs weak" (wtf? If you can snowboard for more than 2 hours your legs are strong enough to ollie).
You don't even have to get good at it, but teaching your body the concept, and trying it a hundred times or so, you will move past that initial stage where it doesn't resemble an ollie one bit, to where you can at least understand where you are trying to go. At this stage, moving to snow will already really benefit from skate practice.
Hint: Ollieing a skateboard is harder, trickier mechanics, but if its not worth learning you can just resign yourself to ollieing your snowboard less well
