How to change BIOS/UEFI settings when keyboard is disabled during boot

During debugging a Linux boot problem, I disabled USB power on boot in the BIOS. This was effectively an irreversible change, since I can't enter the BIOS anymore now. My motherboard is Asus Z97-A. I can currently boot into Windows on this PC (Linux is #2 in the Grub menu, so I can't select it due to the lacking power to the keyboard). My keyboard is wireless, in case that's relevant. I don't have a wired keyboard.

How can I enter the BIOS so that I can re-enable USB power on boot? Is this possible to change directly from Windows? I tried the "Advanced start-up" from Windows, but "UEFI settings" was not visible in the advanced troubleshooting options when I restarted.
