My 2 month old puppy is getting pretty aggressive day by day.

I have a 2-month-old Rajapalayam puppy (a sight hound breed) showing strong territorial aggression and frequent biting. He tries to bite when I show affection or interact, which worries me a lot. He is not fully vaccinated yet, so I can’t take him for professional training or socialization outside safely. I’ve struggled with managing his aggression and biting, especially given the breed’s natural hunting and territorial instincts. I’m looking for practical guidance on managing and reducing this aggressive, territorial biting behavior safely at home while waiting for vaccinations, as well as ways to build trust and control his impulses effectively.
