How to Change "Setup Prompt Time"?

I have a Gigabyte Skylake H170 motherboard,http://www.gigabyte.us/Motherboard/GA-H170M-DS3H-rev-10
My BIOS does not have a option the change prompt time, or the time at splash screen .
So I want to change it in the BIOS file. Thanks.

@funtomod :
Welcome to the Win-RAID Forum!

If you want to shorten the boot time, you should enter the BIOS and
a) disable all not needed devices,
b) disable CSM and
c) enable “Fast boot”.

I use AMIBCP, I found Setup Prompt Timeout in “BIOS Strings”, but I can’t find it in “Setup Configuration”.

Within the “BOOT” section of the BIOS there should be an option named “Setup Prompt Timeout” (or similar), where you can set the number of seconds to wait for the setup hot key.

@funtomod , using AMIBCP, on “Setup Configuration”, looking for “Setup Prompt Timeout” under “Boot Configuration” tree, it should be there. If you find, you can change the default value.

Edit: I tried to find that, but I didn’t find it either. Perhaps, it’s only a forgotten string in the Setup module.
