I think that's a misreading of Trump, if it's even really possible to read him by statements alone.

Trump says a lot of things, but I am assuming he wants to be "hands off" in the sense of not interfering in Israel's affairs and preserving the status quo, rather than cutting Israel off from American support. Much of his voter base is staunchly pro-Israel, so it would harm his support if he were to break that core pillar of the Republican party so suddenly.

Looking at his actions during his previous presidency, he did demonstrate that he was a strong ally of Israel, going so far as to move the US embassy from Tel Aviv to the contested capital of Jerusalem/Al Quds, which is something that had not been done before by any previous administration. Not like Biden made any moves to take the embassy out of Jerusalem either, but Trump effectively cemented US approval of Israel's expansionist practices by placing American affairs directly in the middle of it.
