I've tried a lot of things with eggs, but one time I threw them in my Air fryer - 150°C for 15 minutes and then in cold water. It's so easy method, they almost never break and I get so consistent results I have not tried anything else after. Air fryers, eggs and cook level preferences are of course not the same for everyone so you might have to try around little bit, but IIRC I got the perfect result on second try.
