    What problem are you having with the BIOS firmware already installed? Jack E/NJ

    i want to use dual boot (windows 10+ MacOs High sierra) for that I need some functions to be disabled in bios. 
    but the fun part is that there isn't those function in the bios which I have to disable.
    my current version of bios is 1.21 and I want to update it to version 2.03 which is the latest version

    A Bios update will not give you more options. It's purely security and functionality.

    Do you have multiple Drives or partitions?

    Do  NOT try to update the BIOS to v2.x as it may brick your machine with that kind of error message. The EFI partition must be at least 200MB for proper mounting. Follow these directions for mounting in this link to avoid any issues with the BIOS firmware changes or modifications. https://www.insanelymac.com/forum/topic/332563-success-acer-aspire-v-15-v5-591g-55tu-high-sierra-dual-boot-windows/
