Most mobos usually have a bios flash utility in the bios setup itself, so you don’t need to rely on the windows installer. You just need to stick the update on a USB stick (extract the binary file from the zip).
Hmm I wonder if you could boot into a recovery version of windows to run the bios updater in that case. Like a recovery partition that isn’t even on the main disk.

Sadly that’s only common for desktop PCs, with laptops it’s a lot less common. But many can be updated from within Linux nowadays
