All of the banded geckos I've seen (irl so far) were tame. So it's possible for sure. But because of how fast they are, just try to hold them in their cage, trying to keep them closer to the ground so they don't have a drop. Just keep putting one hand in front of the other and let them walk from hand to hand. This is normally how I tame most of my geckos and it works out just fine for me. It can take a while, though. Another thing you can do is put the tank in an area where they see you more. However, if they already don't fear you and run away every time they see you, it shouldn't be overly hard to tame them.
Just a tip though, just because the gecko is starting to seem tame and will sit still on your hand for a little while, you shouldn't assume they wouldn't try to jump off from a tall place if given the chance, so be sure you always have the gecko secure if you take them out of the cage completely.
