LarkBox X Intel i225-v firmware update

To solve the issues of lan disconnection on the box, we need a bios update, as stated here:

Is there any possibility of having it?
Or we have to create it by ourselves?

I’m sure 99.9% that we cant update the BIOS as Chuwi does not provide any BIOS, drivers and apps for their systems. They just put together some hardware or just brand some generic ones, and sell it.
