Updating the thread with a solution (ish): After all the of random troubleshooting that was performed, the very last thing that was discovered is that the USB-C port must be damaged where the connectors do not fit in correctly.  I was able to get the 4K 60hz display working correctly with a USB-C to DisplayPort cable by holding the cord UP on the port a certain way. While the connector is pushed upward into the port, the display is working as expected.   What I can't answer is if it any of the 40 changes I made during the troubleshooting process had any impact or not in the end result.
So after doing more research I found that the Intel 620 graphics should be able to support 4K 60hz with DisplayPort over USB-C.   After spending about 24 hours of total troubleshooting time, I'm completely baffled.  With a USB-C to DisplayPort cable, I was able to get it working twice.  Monitor was set to 4K 60hz two times now and failed after I left and came back later in the day.  I have done just about everything imaginable to try to make this work.  BIOS, Drivers, scouring the internet from every post ever created on this topic.  Nothing. When I did get the 4K display working correctly, it's when I closed the lid once.  Magically worked.  Never again.  The next is when I was uninstalling monitors in device manager.  Then it magically worked again.  Since then, nothing. I've tried 3 different connection methods: USB-C to both DisplayPort and HDMI.  Also a USB-C to HDMI adapter.  I have no ordered a Plugable dock with DisplayLink to try this as well which will be here tomorrow. The display is detected, but listed as "Display 2 isn't active".  Trying to enable through the Intel Command Center does nothing. Judging by the fact this worked twice at one point, it HAS to be supported.  Something just has to be terribly wrong with a driver or software update somewhere. Any help would be appreciated.  Thank you!
