I solved rewriting street on di.xml
:
...
<type name="Magento\Checkout\Block\Checkout\LayoutProcessor">
<plugin name="rewrite-street" type="Vendor\ModuelName\Model\Checkout\LayoutProcessorPlugin" sortOrder="10"/>
</type>
...
And my LayoutProcessorPlugin.php
:
<?php
namespace Vendor\ModuleName\Model\Checkout;
class LayoutProcessorPlugin
{
/**
* @param \Magento\Checkout\Block\Checkout\LayoutProcessor $subject
* @param array $jsLayout
* @return array
*/
public function afterProcess(
\Magento\Checkout\Block\Checkout\LayoutProcessor $subject,
array $jsLayout
) {
$jsLayout['components']['checkout']['children']['steps']['children']['shipping-step']['children']
['shippingAddress']['children']['shipping-address-fieldset']['children']['street'] = [
'component' => 'Magento_Ui/js/form/components/group',
//'label' => __('Street Address'), I removed main label
'required' => false, //turn false because I removed main label
