i would leave it alone. the brood will hatch out and as we go toward fall, the bees will backfill the honey supers with honey. if they do not, you can just cut the brood out before you extract.
the more you mess with them, the more you slow them down.
you could use an excluder or use one sideways, but you'll have to figure out where your queen is first. excluders tend to slow down the works, so that's a consideration.
