I think not but train the vine around the verbena. Once the small pumkins appear remember to sit on them like a chicken on an egg for at least 6 hours per day.

And it you have more than 4 you will have to recruit help for pumkin sitting.

I've occasionally cut back foliage, but you don't want to cut back too many leaves at once because the leaves are the photosynthesis factory that give the plant the energy it needs to ripen the pumpkin. I'd cut back only what I absolutely have to, and otherwise attempt to train the vine to grow away from the lemon verbena.

You guys are so crazy. I don't sit on my pumpkins. That's the job of the chickens. And, sometimes, the cats. Of course, the chickens are wondering why those pumpkins never hatch.
