Not as far as I know? Egypt does control access in and out along their own border, as every country does, but afaik the nature of that control is at least somewhat dictated by agreements between Egypt and Israel. As far as I know Egypt does not do any of the other things I listed, like controlling what can go in and out of Gaza through borders that aren't their own, nor do they make military incursions into it or bomb it. Also, and I think this is actually pretty key to the idea that Israel believes the land of Gaza to be part of Israel, if Egypt were to invade Gaza do you really believe that Israel would allow that to stand? If Israel truly considered Gaza a state not under its jurisdiction, Egypt annexing Gaza would likely be a welcome outcome.
