There's no option to change DNS in Sercomm AOT-4221SR afaik. You can configure DNS of your choice on every device that connects to the router.

Disable IPv6 from the router. Set it to IPv4 only. That should resolve the issue most probably.

@rajat_ @Pranay62 Can you guys share the Software version of your Airtel Router? Is the WAN page still changeable for you guys?

better buy any external router from brands like TP-Link, Tenda, Netgear etc and put sercomm in bridge mode and dial PPPoE on your own router.
