Yes. To make a vegetarian boil, use the same broth base that you use for the seafood boil: onions, garlic, celery and spices. In addition to potatoes and corn, use plant-based sausages. Be sure to brown the sausages in a pan to firm them up before you slice them for the boil. I like to add green beans to the vegetarian boil. You can also add eggs. Give them about 10 minutes to get hard boiled.
