Bridge mode in D301 (netlink N2801ZEB)

I tried many ways (reset to default with dhcp disabled, ip mode etc, Does the Netlink V2801SG GPON ONT (non-wifi, 1 gigabit ethernet port) have bridge mode? | Routers - Modems - Dongles ) to connect via bridge mode but not yet succeeded, please help me .
my onu interface looks this, no option to enable bridge mode on my device, my connection requires VLAN.

Delete all WAN profiles, it's in transparent bridge mode by default.

If there is a VLAN that you need to use, that must be configured on the main router.

I think Kerala Vision does mac binding, so you'd either need to reset it or clone that to your main router before PPPoE auth happens successfully. You can get rhe currently active mac from the KV user portal.
