Short answer is, no. Keep in mind there's no way from me to check for headcanons or a particular RP that players have. She's a zealot and doesn't distinguish between bloodthirsty monsters and morally conflicted vampires.
If you really want to have her along for your playthrough, you could try that Celestine villains patch someone made on The Mod Site That Shall Not Be Named™. How you want to justify that to your character is entirely up to you, that's not my business, I'm just talking about it from a technical standpoint to stop the confrontations occurring.
Keep in mind, however, that I had nothing to do with that and don't endorse it. Any issues you'll need to speak with the author about.
