are you looking for the PPPC settings for DLP?

I do have that baked in. It is using Microsoft's Schema, the section for Device Control requires a JSON string. I think my JSON is wrong since further troubleshooting with mdatp device-control policy rules list is showing as empty.
I see they have some examples that I had tried modifying and they have scripts to convert from previous, but am I wrong that it doesn't not look like they have great guidance on configuring via that method from scratch? Are there better alternatives that do seem to work well?
I've decided against DLP in the past, but it seems you're right - the policy JSON in turn needs another JSON string defining device control. You'd pretty much need a schema interpreter within the schema json for MDATP.
Like I said, I haven't done this, but it seems the schema you need for the DC JSON is here, rather than where you linked:
mdatp-devicecontrol/device_control_policy_schema.json at main · microsoft/mdatp-devicecontrol · GitHub

I have managed to get it working with only the most minor tinkering of their JSON examples. Any time I tried to get it more to exactly what I would need, it would not deploy as a device control policy to the endpoint. However, as I need to potentially white list devices, I definitely will be needing to modifying significantly more so maybe I'll go back to trying to implement their schema, as I had tried that particular schema in tandem with their broader schema previously, without success. Maybe a change I had made in another spot ultimately became what got things working. Thanks for reminding me of that separate schema.
And I totally wish I could decide against DLP... I'll leave it at that

Could you share what you have done to get this working?

DLP isn't bad....
...users are. :D
