Change attribute data for a store - Magento 2 - magento

Question

I have created a custom attribute for customer using InstallData in magento 2.
However I wanted to change the is_required option of the attribute store wise.
updateAttribute can do the same however I don't know how to use it store wise.
$customerSetup->updateAttribute('customer', 'tax_exempted', 'is_required', true);
Code Snippet to create attribute.
namespace xyz\abc\Setup;
use Magento\Customer\Model\Customer;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
/**
* Install attributes
*/
class InstallData implements \Magento\Framework\Setup\InstallDataInterface
{
/**
* #var \Magento\Customer\Setup\CustomerSetupFactory
*/
protected $customerSetupFactory;
/**
* #var \Magento\Eav\Api\AttributeRepositoryInterface
*/
protected $attributeRepository;
/**
* Init
*
* #param \Magento\Customer\Setup\CustomerSetupFactory $customerSetupFactory
* #param \Magento\Eav\Api\AttributeRepositoryInterface $attributeRepository
*/
public function __construct(
\Magento\Customer\Setup\CustomerSetupFactory $customerSetupFactory,
\Magento\Eav\Api\AttributeRepositoryInterface $attributeRepository
) {
$this->customerSetupFactory = $customerSetupFactory;
$this->attributeRepository = $attributeRepository;
}
/**
* DB setup code
*
* #param \Magento\Framework\Setup\SchemaSetupInterface $setup
* #param \Magento\Framework\Setup\ModuleContextInterface $context
* #return void
*/
public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context) {
/** #var \Magento\Customer\Setup\CustomerSetup $customerSetup */
$customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);
$setup->startSetup();
if ($customerSetup->getAttributeId('customer', 'tax_exempted') === false) {
$custAttr = $customerSetup->addAttribute(
Customer::ENTITY,
'tax_exempted',
[
'label' => 'Is Tax Exempted',
'type' => 'int',
'input' => 'boolean',
'default' => '0',
'position' => 71,
'visible' => true,
'required' => false,
'system' => false,
'user_defined' => true,
'visible_on_front' => false,
]
);
$taxExemptedAttr = $customerSetup->getEavConfig()->getAttribute(
Customer::ENTITY,
'tax_exempted'
);
$this->attributeRepository->save($taxExemptedAttr);
}
$setup->endSetup();
}
}

I found a solution to this, sharing the same below.
//Fetch all websites
$websites = $this->_storeManager->getWebsites();
foreach ($websites as $website) {
//fetch the attribute
$customAttribute = $this->_customerSetup->getEavConfig()
->getAttribute(
\Magento\Customer\Model\Customer::ENTITY,
'tax_exempted'
);
$customAttribute->setWebsite($website->getId());
$customAttribute->load($customAttribute->getId());
//for options that are website specific, scope_ is prefixed while changing
$customAttribute->setData('scope_is_required', 0);
$customAttribute->setData('scope_is_visible', 0);
/** For xyzwebsite, show the attribute */
if ($website->getCode() == 'xyz') {
$customAttribute->setData('scope_is_required', 1);
$customAttribute->setData('scope_is_visible', 1);
}
$customAttribute->save();
}
