Yes? I mean it depends on a reason you're a vegan in the first place whether it's an issue in the first place. If you're are a vegan for sake of being healthy, then unless you've requirement for a partner to maximize their health it won't be an issue. If you're environmentalist vegan or animal welfare vegan then it really depends on how strict or selective you're with people you hang out with. From logical perspective it's not like you're contributing to environmental destruction or animal harm by engaging in a relationship with such person as such person wouldn't be vegan in the first place. Meaning unless you're funding such person then it doesn't contribute to either.
I also reject notion that vegans (as collection of individuals) don't want to hurt anyone. Vegans are diverse group of people that pretty much share one commonality, it's abstinence from consumption or use of animal products. Meaning Vegan could be a neo-nazi desiring a genocide of specific group or more of people, misanthrope that hates humans and perhaps likes idea of their extinction, ideological fanatics that desire to inflict violence on those who don't adhere to their ideology and many others types of people that would like idea of harming someone. I suspect most, if not all absolute pacifists at some point struggle at some point with desire to reach for violence, even if in self-defense or defense of others.
You know or you could just attempt to convince person just like any other person by making an arguments either for animal well-fare, environmental or health benefits. Assuming you know such person decently you would also have advantage of knowing their views, values and principles that would help you construct argument that would help live them accordingly to their values by going vegan. Of course, if there is no contradiction between lifestyle and moral and value system, you lack sufficient evidence or knowledge to showcase contradiction or you encounter persistent cognitive dissonance in person then there is little you can do in that regard.
