Shall I cut ties with narcissistic family members? Is it biblical?

So here is the thing: I can’t take their shallowness,criticism …anymore. I just want to have peace,they already hurt me enough . Enough is enough but ! : I do get along with my aunt and one uncle of my mother’s side (who is a pn ). Is it a good idea? Some of them claim to be christians and seemed to have a genuine faith but I don’t want them on my social medias anymore.
