As you asked how the ajax validation can be disabled for the captcha i tried this way. But i am not sure if this is the correct way.

I have set to the the form with this settings

'enableAjaxValidation' => true,
'enableClientValidation' => false,
'validateOnSubmit' => false,

and changed the validation on the action to this (i removed my captcha in my case 'verifyCode' from the attributes which should be validated.

if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {
        Yii::$app->response->format = 'json';
        $validateAttributes = $model->activeAttributes();
        $key = array_search('verifyCode', $validateAttributes);
        if ($key!==false) {
            array_splice($validateAttributes, $key, 1);
        }
        return \yii\widgets\ActiveForm::validate($model, $validateAttributes);
}
