How long did you hold the button before you had a hard shutdown on your old computer? I've never heard of being able to disable this feature. What I've seen that can be changed is what happens when you press and release the power button for a moment. I don't know if there is a standard default setting but mine is set to shut down. Often, if I can't shut down using the keyboard for some reason, pressing and releasing the [power button will shut down the machine. A hard shut down should only be done when other methods fail. I always try a momentary press of the power button first and wait to see if a shut down occurs. I have to hold the power button down perhaps ten seconds for a hard shut down to occur.

I don't use Windows 10 and while I might be able to tell you where to find power settings, I'd be guessing based on Windows 7. But if you know how to use the start menu search, try using it and searching for power settings if you want to look for them before you receive specific instructions. The start menu search is invaluable for finding things quickly and easily.
