I don't think it's possible to secure a contract with such favorable terms that you can not get cut off for inciting physical violence on government property. OP would also need to be a fairly large player to able to negotiate favorable terms with someone like AWS to begin with.

Not only is it not possible in the pragmatic sense, I don’t think its legally possible, since knowingly carrying such content is quite often criminal (not just for you, but if the higher-level vendor knows about it its criminal for them), and a contract to commit a crime is usually void.
