If Windows overwrites your EFI partition then you won’t be able to boot into grub. It absolutely happens, I’ve had it happen with my main computer within the past year.
It technically shouldn’t happen unless you don’t create a separate EFI partition for your Linux install.
It is generally recommended that you create a separate EFI partition for Linux specifically so that windows cannot mess with your Linux install when it updates.
I could see a bios update having some affect though.
