is there a way to create custom validation rules that can be reuse for Livewire without using Form Request in Laravel?

Since laravel can use custom validation rules when using Request validation

public function store(ModelStoreRequest $request) {
      //
}

is there a way to reuse a custom validation rules without using request ? I am using a livewire and it doesn't need to use request.

public function store() {
     $this->validate([
        'foo' => 'required'
     ]);
}
