Has anybody been able to successfully enable bridge mode on Reliance Jio Fiber's ONT?

I'm interested in getting Jio Fiber, for load balancing purpose with my current BSNL FTTH connection.

But of course, that wouldn't work unless I could use Jio Fiber in bridg mode.

BSNL FTTH is working perfectly fine in bridge mode on my own ONT, which I bought myself.
