Is it possible to install a BIOS update from an .exe file?

[torspedia]

Have you tried just going into the UEFI setup yet? The videos on the Acer website of their process show the Windows part of it as simply automatically rebooting into UEFI setup with the particular file already selected for update; it's still the UEFI that's doing all the work.

Yes, I have, but haven't found the option to boot from the .exe file, that I have on a FAT32 formatted USB.

I haven't looked at the videos on the Acer site yet, so will have a shufty, ta!

Many older Acer, required you to set an UEFI password to open up additional settings. Some now require control-S.
Never lose that password or you may have a brick, or reset to blank when done making UEFI setting changes.

Acer Swift 5 (2019) ctrl-s in UEFI required to be able to change to AHCI mode.

This is correct.
I recently had to discover this fact.
The safest option is create the password ,make the changes and then set the password back to blank when done ,as Oldfred suggests
