How do I modify the Sign Up form "First and last name" label for the displayName property?

Is it possible to modify the label "First and last name"?
The firebase documentation doesn't explicitly refer to the displayName property as a First and Last Name property, I'd like to change my label to something else.

Start with the FirebaseUI Web React Sign Up form and the Firebase documentation for the displayName property. Determine whether the “First and last name” label is configurable and identify the form entry point involved; done means the requested label can be changed without altering unrelated sign-up behavior.
