Unattended Install without S-Mode??

Hi, I've been struggling with creating and unattended install of Win 10 Pro that doesn't then boot into S-Mode. The computers came with OEM Win10 Pro but when I try to do a clean install I end up in S-mode. I managed to get it to work correctly once but the odd thing is the next time I used that same install on the next laptop it did it again.
I've found plenty of articles on enabling S-mode but the only disabling info I've found is how to do it through the Windows store after you've installed. And it looks as though you can't disable it without setting up an MS account anymore. These are new HP laptops so doing a Sysprep as they are doesn't work. If you try to it logs you into sysprep mode as normal but then soon after automatically starts the generalize and reboots before you can do anything. And If I try to kill the process before it reboots it breaks the install.

Any ideas or tips? Do I need to use a different Key in my unattend or something? I've tried multiple keys in my unattend including the standard generic ones ending in T83GX and 3V66T in both the specialize and WindowsPE section just to see if that's where I was messing up.
