ISO keyboard layout in a Mac client

Hi,
I'm running a Mac Sierra client in a Mac Mojave host. My physical keyboard is a ISO one. In the client, I have an ANSI layout, and can't find how to force it to recognize the ISO layout.
Is there a way? I know this is difficult also with a non-emulated Mac, but maybe Parallels has an easy way to do it.

In the Mac Sierra client I've done the usual wizardry (delete the Library/Preferences/com.apple.keyboardtype.plist file, and the restart) with no success. The recognized keyboard is still ANSI.
Is there any hidden preference, in Parallels Desktop, to force the Mac client to recognize the physical keyboard as an ISO one?

Hi, I've not been able to solve this issue myself. Any help would be really welcome!
