Addressing first the issue, rather than the direct question

So how can I enter the advanced boot menu during the Windows 10 start-up sequence in order to discard the hibernation state ?

This is a step which is not actually needed. If Windows fails to recover a hibernation state, it will automatically resume with a normal startup.

The issue that happened to you rather is connected to the fact that you've configured your power button to send Windows into hibernation, instead of shutting it down.

So, every time you tried to turn it on again, it resumed a somehow corrupt system state from hibernation: the hibernation was resumed correctly, but you just continued to hibernate some sort of endless system loop.

The correct thing to do when the system is not recoverable through Ctrl+Alt+Del is to force-shutdown by pressing the power button for 10-15 seconds. Once this is done, Windows will detect it wasn't shut down correctly, and will resume from scratch (and there will be no hibernation state which needs deletion).

Side-Notes:

I agree that force-crashing Windows 3 times is a bad idea, especially when it is totally unnecessary.

Usually, when Windows is in an endless loop, at some point there will be no more hard-disk activity going on: that's the right moment to long-press the power button.

Sending Windows 10 into hibernation makes only sense if you want to retake your work session exactly from where you left it. Otherwise, for system stability it is much better to use the built-in hybrid startup you mentioned in your question.

Answering the direct question

• create a Windows Installer on USB
• Change boot sequence in BIOS so to boot from the USB
• Once the installer has started, select "Repair your computer"
• Enjoy recovery mode

Just create a new shortcut with:

shutdown.exe /r /o /f /t 0

shutdown /?
/r      Full shutdown and restart the computer
/o      Go to the advanced boot options menu and restart the computer.
/f      Force running applications to close without forewarning users.
/fw     Combine with a shutdown option to cause the next boot to go to the firmware ui.
/t xxx  Set the time-out period before shutdown to xxx seconds.   

Update:
OP mentioned his laptop is crashing and can't even boot, so the original question is deceiving.

For that case, this would be more fitting answer:

You just have to keep at it.
Because it's a laptop, it's harder since you don't have a reset button.
After Power ON keep holding the button pressed until shutdown.
It's needed 3 times, and timing is everything.

If still unsuccessful you should check out your laptop manual and find what key brings you to BIOS/UEFI setup. Then spam that key as soon as you hit the power button. Once in BIOS/UEFI, disable any Fast Boot options.

Another solution would be to connect an external keyboard - it's usually more reliable.

And finally, connecting a bootable device such as a dvd or usb stick can also break the loop. There is probably also a hotkey to launch a boot menu, such as ESC, F1, F2, F8, F11, F12.
