Or do you mean you'll only speak to them at larger family functions and even then, keep it to pleasantries and otherwise not engage? If it's the former, be careful because you can inadvertently punish the wrong people by making it so awkward that now there can never be a family Christmas celebration again, no 80th birthday party for granny - every thing has to be split up and duplicated. It's like a really ugly divorce never ends.
If you're able to make do with the later, I think the other family members you do want to be on good terms with will really appreciate your maturity.
It'll end eventually. One or the other of the people will die first.
