How Can I Change My Email?

Hello, i apologize firsthand for the newbie question, how can i change my email address?
Currently i’m not linking my google account, and don’t plan to. I simply use an email, and i’d like to change that.
But i don’t see “change email” option DX Only “change password”.
I’ve searched on this forum and i don’t find a solution as well, but i saw the mods changed them. So, can i only change it with dynalist assistance?? If yes, why? D: And how to do that then? (´-ι_-`)
