Hi Swapnil,

Yes, you may add the Shopify Customer id to an existing Customer in NetSuite using the Shopify customer to NetSuite customer (add or update) flow as long as the Customer in NetSuite and in Shopify has the same email address and you are using the default Customer Lookup settings on the Shopify customer to NetSuite customer (add or update) flow.
