How to update BIOS on a system that only use Linux as OS.
Asking this because some clowns at Acer decided that they will only provide BIOS updates through Windows Update.
Edit: I’m not talking about installing the BIOS file. They don’t even provide BIOS file in the first place.
There is no universal solution to this. Some vendors support fwupd (LVFS) on some hardware (Dell, Lenovo), some allow to update via a file on a USB stick (Asus).
Unless it is a system from Linux first company (Tuxedo, StarLabs, System76, Slimbook) expect to manually check what the specific model you are looking at supports.

Also, I don’t think fwupd has firmware for this particular laptop. ( Acer One 14 Z2-493 )
That’s the thing - there is no option to update BIOS on Linux then.
You must install Windows or maybe use one of those unofficial Windows Live USB images.

Indeed that’s IMHO the solution, namely prioritizing ecosystem that genuinely see Linux as something valuable, with an addressable market, rather than a cost linked to annoying users.
I had an Acer laptop once. I had Ubuntu on it. I had problems with random crashing after a few minutes, I ran memtest, it took a few hours for a full test and came back with a whole slew of faults. I sent it to Acer under warranty and they told me that Linux was the problem and I should leave windows on it.
I called the “technical” support regarding this issue. And they said they’ll only support Windows.
Making your entire hardware reliant on particular proprietary software like Windows is just stupid.
Never buying Acer again.
At this point, I don’t even know which vendor to buy, when everybody is shit.
Tuxedo, Framework, Slimbook, System76, Starlabs are Linux-first vendors with an excellent track record.
Install windows on a second/spare drive. Boot PC from this and run their tool.
I know you’re trying to find a way around not using windows, but if the vendors only solution involves it, I wouldn’t trust any hacky workarounds when it comes to bios updates.
All the security updates are in the microcode loaded by the bootloader even before the kernel is loaded, so unless there’s some new feature, bugfix, or hardware support you specifically know you need it’s not important to update your BIOS anyway. Which is good, because as far as I can tell you’re just screwed by a bad hardware vendor.
Is there an option to save the new bios update file to a USB stick, then enter bios and trigger an update manually that fetches the file from said USB stick?
I’ve done it this way with an Asrock motherboard for desktop running Bazzite.
