[Vuejs]-Vuetify with multiple forms in a page. Disable submit button on each form till validation rules criteria is met on that form

Why not use a different v-model value for each v-form? Do you have an undetermined number of forms?

If you need to check all validity, you can create a computed data/method that checks all of them.

computed: {
  allValid() {
    return this.validFormContact && this.validFormPreferences;
  }
}
