Unfortunately, there is no Apple DDM. Check the supported operating system list on the UP2718Q driver page. When you change from a Windows operating system to either Apple Mac OS or Apple MAC OS 9, the DDM listing goes away.
Thanks for your prompt response. I'm sad to hear that there is no DDM support for Apple. If I visit the UP2718Q support page, it does show that the monitor does support Mac OS, but no drivers nor software are listed for the monitor. If you find out any new information regarding macOS support for this monitor or any way that I can use this monitor productively with macOS please let me know.
We do not have a Apple DDM for either monitor (UP2718Q, U2718Q). Your best bet is to ask the Apple users on their Forum. Perhaps they know of a specific USB-C to DP or USB-C to mDP cable that they have tested.
