Fraud/scam

Hello! Need suggestion/help on how to catch and prevent fraud.

We use Shopify and recently, our team has tracked potential fraud involving scammers based in Florida.

They order fine jewelry using different cards, names, and emails. The same people are signing for deliveries but the real card holders initiate chargebacks atterward.

We already have Shopify protect, but if there are workarounds within Shopify or 3rd party tool anybody can suggest please, it will be greatly appreciated!
