Change serial in ami bios


i’m pretty new at this modding bios, so hope someone can help me with this problem

I got a Chuwi Hi12 dual boot tablet, i use some apps in android for my work that need to be registrered with the tablets serial, but somehow in the past Chuwi made an update that set the serial in bios to 0123456789ABCDEF, so now i can reg the appz curse someone already used that serial

So here its go, how do i change the serial to the serial my tab have?

Or are there maybe a script that will change it, where you for exampel have an xml file where you put in your serial, then run the program and it changes the thing, would be a great thing that also could help other in same problem

Some have already asked the question at Chuwi board, but they seem to avoid answer that question

So please, we really need some expert help here
