Is there any way set isValid to true when onKeyDown or onChange event

[EkaLinMan]

Now I use onSubmit mode, it always executes the validation when submitting. It means the form state is invalid after the first incorrect value was submitted until the user submits the correct value next time. But I hope the form is valid when the user starts to key anything, is it possible?
const formContext = useForm({ defaultValues: {searchString: ""}, mode: "onSubmit", reValidateMode: "onSubmit" });
