What does "disabled" do in UseFormProps?

[Toshinaki]

As stated in the title,

react-hook-form/src/types/form.ts

Line 107 in 03f9d72

export type UseFormProps<

we can see a disabled props in UseFormProps,
however, I found nothing about it in document
https://react-hook-form.com/ts#UseFormProps

What exactly does this prop do?

I can see that input fields are disabled, if useForm({disabled: true}), but not the submit button.

I would like for it to be an official thing and disable all input fields, but I get this symptom when I use it.
