Request XB7 or XB8 swap for 1 Gig EPON - XER10 does not support bridge mode

I have 1 Gig EPON fiber service (installed 2026-06-02), with a Nokia NKFN11AEL ONT (Nokia part 3FE48103AAAA). The tech delivered an XER10 gateway (Part No SCER11BELCOM, FCC ID P27XER10).

I run a UniFi Dream Machine SE as my primary router. The XER10 does not support bridge mode, which forces me into a double-NAT setup. On 1 Gig service, an XB7 (CGM4331COM) or XB8 in bridge mode would saturate the line and let my UDM handle routing, firewall, and DHCP cleanly without double-NAT.

Could you swap the XER10 for an XB7 or XB8? Happy to provide my account details and full hardware info by DM. Thanks.

Following up - all set on my end. The XB8 arrived, I put it in bridge mode, and my UniFi router is now the edge with a clean single-NAT setup and working IPv6. No further action needed. Thanks very much for arranging the swap.
