    This is usually first procedure I do for new hardware, because
    products nowadays are rushed to the market, so internal firmware for
    all kinds of devices is often poorly tested.

    I think fastest and easiest way is to swap current disk with another
    (if it is available of course) and install Evaluation version of
    Windows 10 Enterprise. [1]
    This version doesn't require a product key or activation.
    Some BIOS\Firmware updates could be installed from WinPE (or WinRE)
    environment, but I doubt this one from Acer could run on WinPE,
    because it is bundled with a driver, along side with a few
    executable binaries and shared DLLs.
    
    Another viable option, because you've got a drive image of
    preinstalled Windows 10, is to save an image of current drive and
    restore from the image with preinstalled Windows OS.
    And after BIOS is updated, restore from the saved image with latest
    data.
    Clunky solutions, but I think there are no other options, because
    apparently Acer hates GNU-Linux. :\
