Try following way:


protected $eavAttributeFactory;
protected $attributeOptionManagement;

public function __construct(
    \Magento\Eav\Model\Entity\AttributeFactory $eavAttributeFactory,
    \Magento\Eav\Api\AttributeOptionManagementInterface $attributeOptionManagement
) {

    $this->eavAttributeFactory = $eavAttributeFactory;
    $this->attributeOptionManagement = $attributeOptionManagement;
}

And then


$magentoAttribute = $this->eavAttributeFactory->create()->loadByCode('catalog_product', 'test_attribute');

$attributeCode = $magentoAttribute->getAttributeCode();
$magentoAttributeOptions = $this->attributeOptionManagement->getItems(
    'catalog_product',
    $attributeCode
);
$attributeOptions = ['Test2', 'Test3'];
$existingMagentoAttributeOptions = [];
$newOptions = [];
$counter = 0;
foreach($magentoAttributeOptions as $option) {
    if (!$option->getValue()) {
        continue;
    }
    if($option->getLabel() instanceof \Magento\Framework\Phrase) {
        $label = $option->getText();
    } else {
        $label = $option->getLabel();
    }

    if($label == '') {
        continue;
    }

    $existingMagentoAttributeOptions[] = $label;
    $newOptions['value'][$option->getValue()] = [$label, $label];
    $counter++;
}

foreach ($attributeOptions as $option) {
    if($option == '') {
        continue;
    }

    if(!in_array($option, $existingMagentoAttributeOptions)) {
        $newOptions['value']['option_'.$counter] = [$option, $option];
    }

    $counter++;
}

if(count($newOptions)) {
    $magentoAttribute->setOption($newOptions)->save();
}
