Don't present it as a problem, just a point of information. If he makes an issue of it, then start job hunting - even if just an internal move or temporary secondment.
I disagree with PPs who say this is not the manager's problem - having someone quit and need to be replaced is typically a problem. It's a hassle, and it makes the new manager look bad that someone who was previously performing walked away because new manager wouldn't reschedule his daily standup or whatever. Reasonable managers are willing to work with reasonable employees. But your real leverage depends on how badly they need you and how easily you could leave.
This. And block off your calendar for when you need to leave the office. Of course be available to meet over lunchtimes (does anyone even take "lunch" any more?). As a manager, flexibility is key. Love workers that are at it early with only maybe a cursory check after the commute home. Personally, I have a very early start, then a gap, then I get a ton of things out and communicated for the next day for my team in an earlier timezone. It's super efficient.
