React formik form validation: How to initially have submit button disabled

Question

Below is my React form validation code in which I am using formik. By default when the form loads, I want to keep the submit button disabled:

To have the button initially disabled just check if the touch object is empty and keep it this way until all the fields are validated with !isValid

disabled={!isValid || (Object.keys(touched).length === 0 && touched.constructor === Object)}
