No? Atheist literally is A-Theist, similar to amoral being A-Moral ("a" being a common prefix for "anti" or "opposite"). A-Theist means one does not believe Theism, the "belief in the existence of a supreme being or deities."
In which case, by believing in one specific God, one is not an atheist in any sense toward other religions. Believing in one specific God literally means that you do have "belief in the existence of a supreme being or deities," your only dispute is to which one.
Note that a- is a different prefix than anti-. a- means "without", whereas anti- means "the opposite of". So, being a-theistic means that you are "without god(s)". Being anti-theistic would meant that you oppose god(s). An amoral thing is a thing to which morality doesn't apply (for example, weather phenomena are amoral). Anti-moral would mean something that is opposed to morality, which would probably make it immoral (such as a human killing another human that hasn't wronged them in any way).
