Xb8 to XB10 upgrade

Hello, I currently have an XB8 gateway with Xfinity's symmetrical 2 Gig internet plan (2,000 Mbps download and upload) in ZIP code 94122.

I'd like to upgrade to the XB10 WiFi 7 DOCSIS 4.0 gateway.

Can you confirm whether my service address is FDX-enabled and eligible for an XB10? If so, can you arrange an equipment exchange or shipment, and let me know whether there are any additional fees?
