apples / oranges. You need to look at overall diameter of rim + 2 x tire. And the bike is designed for 4.8" tires, so using smaller tires will drop the BB. if that is relevant depends on your riding.
Gravel bikes,like road bikes, already have lower BB since they typically don't go through rock gardens. Fatbikes on the other hand are like MTB and typically have higher BB, but they also encounter rockgardens and other obstacles that can strike your pedals. Or the pedals strike them, I guess.
