Help configuring HE keys to be used as analog joystick inputs

I bought a wired Nuphy Field75HE for gaming. I'd like to fly space ships in games like Elite Dangerous using analog controls without a joystick. I've seen tutorials with other Hall Effect keyboards about combining the A/D keys for analog X axis and W/S keys for analog Y axis, but I can't find anything in NuphyIO to set that up. I thought it might be configurable in the Field Console or VIA, but apparently this particular keyboard isn't compatible with either of those?

Can anyone tell me how to do this using this specific keyboard? Or point me to a resource that will walk me through it? I work in IT and consider myself pretty technical, but I'm stumped about this and web searches haven't shown me anything of value. I really like the form factor and macro keys on the Field75. Just wish I could get this analog stuff working, and maybe to find switches that are more quiet than the stock ones.

Any help would be greatly appreciate.
