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. :\
