If you've already managed to assert your boundaries and they've failed to respect them, then your boss is failing to listen, do their job, and maybe simply there to collect a paycheck and follow the path of least resistance rather than have a backbone.
Try to have them see the light or you'll need to find somewhere else to be for your own sanity. Maybe bring your boss a copy of the No *sshole Rule by Prof. Sutton.
Never put up with excessive toxicity because silence gives consent and your feet vote. Just as there are many other workers, there are many other jobs.
Yes, I am disappointed with my manager, especially given the number of times and the insistence with which I've raised this. It's clear to me both that he's afraid how this will reflect on him to his manager, and he's afraid of how the other engineer will react. He wants to keep the peace, which means me just sucking this up.
I don't want to leave this job unless I've exhausted all other possibilities. With this exception, it's great.
But the thing for your manager is, if you leave because he didn't handle this, that will also reflect badly on him. And it sounds like leaving because of this is a real option for you. You wouldn't just be saying it to blackmail your manager - you're really thinking that you may have to leave because of this.
