changing video mode hybrid ,bios reset

HP Recommended
hp zbook 15 g2
Microsoft Windows 10 (64-bit)
I have a zBook 15 G2 and to understand why my nvidia k2100 doesn't work,my screen is black after trying to update the BIOS and changing
the hybrid video mode from auto to on or off. Since then, nothing appears on the screen but the laptop seems to boot correctly
(I see the hard drive working to boot) I can't even see the BIOS screen to change my settings.
I started connecting a screen to a VGA port before starting the boot and changing screens but nothing works.
I was thinking about resetting the BIOS but I can't find anywhere how to do it.
I tried WIN + B or WIN + V but it doesn't work
I removed the backup battery, ram, hd. but nothing.
Any suggestions to fix my problem or reset the BIOS?
 thank you.
