Installing using OpenCore and Mojave installer does not show SSD

I have an XPS 15 9560 and for various reasons, I am unable to upgrade to Catalina right now. I thought I would try out OpenCore and install Mojave with it though. I have a good EFI (or so I thought) that boots and works, but when I enter the Mojave installer, my internal NVMe drive is not showing. I did try Catalina just to check it and that sees my drive just fine. Could it be my EFI doesn't include something for Mojave?

The last lines of the Mojave installer logs say something like:

sidebar failed to get physical whole disk
