How to add same name product in magento 2?

I am uploading product programmatically in Magento2 I have same name product with different SKU but when I run script Magento 2 gives an error because of Url Key :

Uncaught PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'reine-de-naples-jour-nuit-8998.html-1' for key 'URL_REWRITE_REQUEST_PATH_STORE_ID

my script is those we use to save a product programmatically

<?php
use MagentoFrameworkAppBootstrap;
include('app/bootstrap.php');
$bootstrap = Bootstrap::create(BP, $_SERVER);
$objectManager = $bootstrap->getObjectManager();
$objectManager1 = MagentoFrameworkAppObjectManager::getInstance();
$directoryList = $objectManager1->get('MagentoFrameworkAppFilesystemDirectoryList');
$path = $directoryList->getPath('media');
//var_dump($path); die;



$state = $objectManager->get('MagentoFrameworkAppState');
$state->setAreaCode('frontend');
$myarray = glob("Book2.csv"); 
usort($myarray, create_function('$a,$b', 'return filemtime($a) - filemtime($b);'));
if(count($myarray)){
    /*This will create an array of associative arrays with the first row column headers as the keys.*/
    $csv_map = array_map('str_getcsv', file($myarray[count($myarray)-1]));
    array_walk($csv_map, function(&$a) use ($csv_map) {
      $a = array_combine($csv_map[0], $a);
    });
    array_shift($csv_map); # remove column header
    /*End*/

    $message = '';
    $count   = 1;
    foreach($csv_map as $data){ 
        //echo '<pre>';print_r($data);exit;

$product = $objectManager->create('MagentoCatalogModelProduct');
$product->setName(trim($data['Name']));
$product->setTypeId('simple');
$product->setAttributeSetId(4);
$product->setSku(trim($data['model_no']));
$product->setURL(trim($data['Name']).trim($data['model_no']));
$product->setWebsiteIds(array(1));
$product->setVisibility(4);
$product->setCreatedAt(strtotime('now'));
$product->setPrice(trim($data['price']));
//$_product->setShortDescription(trim($data['Short Description'])); // add text attribute
//$_product->setDescription(trim($data['Long Description'])); // add text attribute
 $img_url = trim($data['img_big']);

                //$lastWord = substr($img_url, strrpos($img_url, '/') + 1);

                //copy($img_url, 'pub/media/product/');
                $dir = $directoryList->getPath('media').'/big/';
                $imgpath = $dir.$img_url;
                //echo $imgpath; die;
                /*$_product->addImageToMediaGallery($imgpath, array('image','thumbnail','small_image'), false, false); */
                $product->addImageToMediaGallery($imgpath, array('image', 'small_image', 'thumbnail'), false, false);
//$_product->setImage($imgpath);
//$_product->setSmallImage($imgpath);
//$_product->setThumbnail($imgpath);
$product->setStockData(array(
        'use_config_manage_stock' => 0, //'Use config settings' checkbox
        'manage_stock' => 1, //manage stock
        'min_sale_qty' => 1, //Minimum Qty Allowed in Shopping Cart
        'max_sale_qty' => 2, //Maximum Qty Allowed in Shopping Cart
        'is_in_stock' => 1, //Stock Availability
        'qty' => 100 //qty
        )
    );

$product->save();

    }
echo'success';
    }
?>
