How should I prune an overgrown rabbits eye that pretty much a tree?

I bought a house a year ago that has a large blueberry tree growing. About 7’ tall. It doesn’t have any small canes coming from ground level. Just a large single base like a tree almost 4 inches in diameter. There probable five large stems about an inch to 2 inches thick. Almost all the growth is twiggy on it. I know that ideally you’re supposed to have multiple stems/canes and trim back the older ones.

Is there a way I can get canes to come up around it or is that large trunk going to outcompete anything trying to grow? If I take the whole thing down to the ground, will canes come out after a year or so?
