Magento 2 - Set product attribute to use default values - magento

Question

I want to check Use as Default for all product for a particular store view
I use this code
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$collection = $this->_productCollectionFactory->create();
foreach($collection as $data){
$product=$this->_product->setStoreId(1)->load($data->getEntityId());
$product->setData('name',false);
$product->save();
}
But this is removing product from categories.
Can you please let me know how I can check Use as default checkbox programmatically.

Answer 1

Magento 2.1.3 EE
The following solution creates a CLI command to directly manipulate the database and delete store specific product attribute information. It was written for Magento Enterprise edition, so if you're using Community Edition you'll have to modify this code to utilize entity_id instead of row_id.
Please be careful with this. The solution laid forth here bypasses model classes and performs direct delete queries on the default database connection's catalog_product_entity_datetime, catalog_product_entity_decimal, catalog_product_entity_int, catalog_product_entity_text, and catalog_product_entity_varchar tables. Back up your database first.
Step 1: Create the module

Step 2: Enable the module
php -f bin/magento module:enable StackOverflow_Question40177336
Step 3: Utilize your new CLI command.
The command has two required arguments, attribute_code and store. Store can be either the ID or Code. Admin store is not allowed for obvious reasons. The command also has an optional third parameter of SKU if you wish to only target a specific SKU (omitting this applies to all products).
For example, if you wanted to delete all "name" values from the "default" store view your command would be as follows:
php -f bin/magento catalog:product:attributes:use-default-value name default
