Use two 4K monitors on HP Spectre x360 15 - Only 1 monitor loads at a time

HP Recommended
Spectre x360 15t-df000
Microsoft Windows 10 (64-bit)

I'm using a Thunderbolt dock to view two external 4k monitors but only 1 will work at a time.  Is my laptop capable of running both monitors at the same time?  What settings should I be looking at to enable both monitors.

 

It will drive the laptop monitor, 1 external through hdmi, and 1 through thunderbolt dock all in 4k at the same time.  It just won't send 2 through the thunderbolt port.

 

My dock is a Plugable TBT3-UBZ

It will still only drive one 4k monitor through the thunderbolt usb slot and dock.  I am getting a second monitor by using the onboard hdmi slot, and even three with the laptop open.
