There absolutely is; formally speaking, statements can be categorised into normative, saying how things should be, and positive, saying how things are. A politically neutral AI would avoid making any explicit or implicit normative statements.

>...and positive, saying how things are

This presumes that the AI has access to objective reality. Instead, the AI has access to subjective reports filed by fallible humans, about the state of the world. Even if we could concede that an AI might observe the world on its own terms, the language it might use to describe the world as it perceives it would be subjectively defined by humans.

AI simply not openly and proudly declaring itself MechaHitler while spreading White Supremacist lies and Racist ideology would be one small step in the right direction.
