Anyway to disable the flash write protection insydeH2o RSA signed ?

I need to flash older bios,
I finaly got fptw64 working with my laptop,
Thank you (LOST IN BIOS)for you help.
But i can only read my bios and save an image using fptw64.exe -d -bios image.bin.
But When i try to flash the older original insydeh2o bios or even the backup image
fptw64.exe -f -bios image.bin, It returns me error message that write protected can not write to bios.
