Topton N11 board with CWWK NAS board : bios support request

Hello all, I am new to this forum. I am seeking support for the NAS motherboard from CWWK / topton N11 nas. The board name is R7-7840HS as seen on the sticker.

This board has an AMD 7480HS + 9 SATA (1+2X4 thru SFF adapter):

The board was sold by toptonpc but ultimately it is made by CWWK. 

The current bios version is : FMA01_P5C9V06 (AMI bios)

I have described the board here:  https://github.com/oceanborn2/nasbuild/blob/main/hardware.adoc

Can someone point me to the latest BIOS update ?  

I have found the following but not sure:
