Prompt for any key before booting (Rufus)

Hi, I am not sure if what I am experiencing is related, however when I create my ISO I have disabled the option CreateISO / Prompt for any key before booting. Yet, when I boot from my USB stick (burnt with Rufus) I am always asked to press any key to boot from USB (low-res grey text).
This is not a BIOS thing, because when I boot from other bootable USB sticks (eg. GParted, ...) I am NOT asked to press any key, so I suspect it is NTL which does not respect that setting maybe ?
 
There is no setting on the ISO, instead two EFI boot files are provided by Windows. One that requires a key prompt and one that doesn't:
- efisys.bin
- efisys_noprompt.bin

When creating an ISO, NTLite can pick which boot file to copy as as "efisys.bin".

Rufus adds a twist that it uses it's own custom boot loader, which bypasses this normal process. It has a different workaround.
Increase time showing "Press any key to boot from USB" to e.g. 30 seconds?
 
Oh so it is Rufus ! Ok.
Btw, actually there IS a similar setting in Create ISO, see screenshot (but likely it is something else)
 
That's exactly what NTLite is doing, copying one of two EFI files.

Rufus for legitimate reasons (which pbatard goes over in his GitHub issues), doesn't keep the normal boot code and replaces it with a file that he manages. So whether NTLite or another tool has swapped out efisys.bin on the ISO, a Rufus-prepared USB doesn't use it.
