/**

* I have implemented it by analogy with a similar solution for Magento 1.x:
* http://magento.stackexchange.com/a/86146
* @param Model $model
* @param string $attName
* @param mixed $attValue
*/
function df_eav_update(Model $model, $attName, $attValue) {
	df_param_string_not_empty($attName, 1);
	$model[$attName] = $attValue;
	/** @var AbstractEntity $resource */
	$resource = df_ar($model->getResource(), AbstractEntity::class);
	$resource->saveAttribute($model, $attName);
}

It uses the \Magento\Eav\Model\Entity\AbstractEntity::saveAttribute() method.
