OpenWrt support for FiberHome VDSL2 modem HG150-Ub

I have a FiberHome Vdsl2 modem model: HG150-Ub, i was wondering if i can find openwrt for it. i would love to use it as a router (range extender if possible via ethernet or wireless).
This is the picture of it from inside i hope somebody could understand its specs.

Broadcom, that's not a good start ....

i can barely read its written "Broadcom bcm63381ukmmlg"

doesn't seem to be a supported SoC
