Cannot get NUC7I5 out of fast boot mode

[SMayo]

I've tried shutting down and then holding the power button for 3 seconds. I've tried plugging the usb keyboard into the front USB and repeatedly hitting F2. I've tried holding down F2 and booting. In all cases it goes straight to the linux install.

I need to get into the BIOS because I can't get 8 channel audio out of the HDMI and I assume it's turned off there.
