Allow to disable notification that is shown on invalid form submits

[tim-hoffmann]

Is your feature request related to a problem? Please describe.
When a form is invalid a notification is shown on the bottom of the screen. I want to be able to disable the notification.

Describe the solution you'd like
There could be a prop or similar to disable the notification.

Describe alternatives you've considered
I checked the code and couldn't find an option to disable the notification. Only if I create a custom Form component, which wouldn't make much sense, since it would be basically copy paste.
