The startup login screen keyboard always reverts to ABC

This has happened on my M1 Pro MacBook Pro ever since I bought it. It was the same under Monterey. I did not experience this with any Intel-based Mac. I have not found a solution to this problem and it makes the restarts a terrible experience because it threatens to lock me out until I remember that on this machine, I have to always manually select the Dvorak layout I'm using for typing. I've filed a couple of macOS bug report feedback things of this, but this never seems to be solved. It's as if Apple just doesn't care about people who're not using the American keyboard layout. I see many others have the same problem both here as well as on other forums.
