U3219Q, KVM not waking USB Type-C when in sleep mode

I have recently purchased a U3219Q that is connected to two laptops:

1. HP Elitebook: USB Type-C
2. Dell XPS: DP and USB 

- I am using the built in KVM which works flawlessly when I use hotkeys to switch between laptops.
- Both laptops are set to "do nothing" with the lid down and sleep after 1 hour.
- This worked on my previous setup when both laptops were connected to another Dell monitor and I had to toggle the keyboard between USB and Bluetooth depending on the laptop I was switching to.

When the laptops go to "sleep" I can always wake the Dell, but the HP doesn't respond until I pull out the USB Type-C and put it back in. (The laptop remains on and in sleep mode)

Is there a setting on the monitor for waking USB Type-C devices?
