HP Zbook 15v G5 - DP 1.3 out of TBT3 poirt

HP Recommended
HP Zbook 15v G5
Microsoft Windows 10 (64-bit)

On the HP Zbook 15v G5 website under specifications the expansion ports list:!tab=specs


Ports Left side:
1 AC power
1 USB 3.0
1 USB 3.0 (charging)
Right side:
1 HDMI 2.0
1 headphone/microphone combo
1 power connector
1 RJ-45
1 USB 3.0
1 USB 3.1 Type-C™ Thunderbolt™ 3 (DisplayPort™ 1.3)


However, when I try to use DP 1.3 it only allows me to do DP 1.2.  I then checked the TBT3 controller and it was a 2016-vintage Alpine Ridge controller which only supports DP 1.2 instead of what should be a 2018 Titan Ridge controller in this 2018 laptop.  This throttles the output of the Quadro P600 inside the laptop.  How do I go about getting this rectified?
