I don't think so. Theism is a collective term. When a person identifies as a theist, what that person means is that he follows a certain specific religion which includes some type of personal god. Strictly speaking that even excludes deistic religions.
So we're talking about religions like christianity, judaism, islam,..
I'm having a hard time thinking of a theistic religion which does NOT come with doctrines, rules on how to live, claims about the world,...
That would be deism.
Again, I'm having a hard time coming up with theistic religions, that don't.
