We do not allow a user to change their username after an account is created. Is there anyway to express this in the Kratos identity schema such that the UI will set that input field to `disabled`?

Hi <@U017406ACES>
I don't think there is any option like that, maybe you could have a hook that disallows the request on username change
<https://www.ory.sh/docs/kratos/self-service/hooks#web-hooks>

paired with your UI which just doesn't show the field as editable.

I ended up just setting `disabled` to true by hand for `traits.username` when I get the initial settings flow. Not the best, but it works.

I will investigate the hook technique as well.
