Unable to Identify openwrt build for this board

hello, everybody, I have an iball 3g/4g mimo router and want to install openwrt.
I opened the router case and i found board is customized to support only limited feature rather it supports more too.

Is there any compatible build for this board exist?

The RTL8676S probably still isn't supported.

it means, it wouldn't work at all.

That is correct.
