replace XB7 with member owned router on NKFN11AEL ONT fiber network

I have Xfinity EPON fiber service with a separate NKFN11AEL ONT and a rented XB7 gateway.

I am trying to replace the XB7 with my own TP-Link Deco mesh router system.

I have already spent considerable time with phone support. They attempted to register the MAC addresses of three different Deco routers, but their system returned errors.

I believe this requires an account-level change, not standard modem activation.

I am requesting that the appropriate fiber provisioning team:

1. Verify my eligibility for the Member-Owned Router option.

2. Remove the XB7 as the active gateway from my account.

3. Reprovision my ONT to accept a customer-owned Ethernet router directly.

4. Confirm when I can connect my Deco directly to the ONT.

5. Confirm removal of the monthly XB7 rental charge.

I am not requesting bridge mode or cable modem activation. I need the EPON customer-owned router configuration.

Please escalate this to the appropriate provisioning team.
