There are two issues here.
First, should Community be bumping questions? There are specific rules as to when Community bumps a question back to the homepage of a site. Community exists to get more eyes on a question and its answers. The goal is to improve the question so it gets answers, get votes on the question to get even more eyes on it, get votes on existing answers so the question enters an "answered" states, or get answers to questions. Although not stated as an explicit goal, if a question should be closed as off-topic, bumping it to the homepage should allow people to cast down and close votes and put the question into the close vote review queue.
To answer your question, no. Even if the staff could tweak Community on a per-site basis, disabling it would do far more harm than good. It would stop good questions from getting eyes on them, good answers from getting votes, and in some cases, bad questions from getting close/delete votes.
Then, there's the specific case. You make the claim that this question is off-topic. I read the question and I don't see it. I see a question about build and release management (which is on-topic) and versioning (also on-topic). It doesn't require Apple customer service to answer (which would make it off-topic). Just because a question is about iOS (or Java or C# or {insert technology here}) doesn't mean it doesn't belong here if it fits our list of things that are on-topic and doesn't go into the things that we exclude.
