My work provided me with this HP G5 USB-C dock:

I am hoping to use it for my personal Mac as well to reduce desk cable clutter.
I have a Samsung 4k60Hz monitor and an HP 1080p60Hz monitor that I use for work, both connected to the dock via DisplayPort. To get 4k60Hz output with the HP work laptop, I had to go into BIOS and enable high resolution mode over Thunderbolt. As I understand it, this reduces the dock USB speeds to 2.0 to allow more bandwidth for the DisplayPorts. Without that option, I can only do 4k30.
I am hoping to reduce clutter by using the same dock for my personal Mac. I only want to use the 4k monitor with it. While with my smaller, single DisplayPort CableMatters adapter, I can get 4k60 with the Mac, connected via the G5 dock, I'm getting 2560x1440 60Hz.
Is there a method to force 4k60Hz through this dock with the Mac, akin to the BIOS high-resolution mode on the HP?
