How to remove product attribute row woocommerce using code

I have found a solution after some digging in database:

$product_attributes = get_post_meta( $product->id , '_product_attributes' );

                $temp_product_attributes = [];
                foreach($product_attributes as $product_attribute) {
                    foreach($product_attribute as $pt_k => $pt_v) {
                        if ($pt_k !== $attribute_name) {
                            $temp_product_attributes[$pt_k] = $pt_v;
                        }
                    }
                }
update_post_meta( get_the_ID(), '_product_attributes', $temp_product_attributes);

First we need to get all of product attributes then we traverse the array and remove the attribute we don’t want any more (by the way I have store unwanted attribute in $attribute_name).

At the end we save the post meta with new product attributes without the one we wanted to eliminate.

$temp_product_attributes is for saving the attributes we already have.
