The plain USB-C mode is transmitting USB and DisplayPort signals. There is no PCIe support. The only way to get PCIe from USB is using the JMS583 chip from Jmicron which does UASP to NVMe conversion (but will not work with any other type of PCIe device, even PCIe AHCI SSDs).

The Asmedia ASM2362 appears to be similar to the Jmicron JMS583.

This might work with the LG UltraFine 5K display, but you need a GC-TITAN RIDGE to transmit the DisplayPort 1.4 MST signal over Thunderbolt 3 to the HP Thunderbolt Dock G2, then a GC-ALPINE RIDGE or GC-TITAN RIDGE to transmit the two DisplayPort 1.2 SST signals over Thunderbolt 3 to the LG UltraFine 5K display.

I connected the HP Thunderbolt Dock G2 to my Mac mini 2018, connected a display to one of the MST hub ports, then ran the following command to get some dpcd info about the MST hub in the HP Thunderbolt G2 (it doesn't give all the info):

/System/Library/Extensions/AppleGraphicsControl.kext/Contents/MacOS/AGDCDiagnose -a > AGDCDiagnose.txt 2>&1

The OUI for the MST hub is 144-204-36 which, according to http://standards-oui.ieee.org/oui.txt  is "Synaptics, Inc".
I found a DisplayPort 1.4 MST hub that also uses the Synaptics chipset at https://www.delock.com/produkte/G_87737/merkmale.html
A stand alone DisplayPort 1.4 MST hub will be easier to use than the HP dock to connect a dual cable or dual link 5K display to a single DisplayPort 1.4 port of your graphics card because a conversion to Thunderbolt (the only way to get a 4 lane HBR3 signal to the HP dock) is not required with the Delock MST hub. Of course this still will only work in Windows.

One can find an updated article about the TB3 integration into the Ice Lake SOC here: https://fuse.wikichip.org/news/2628/a-look-at-the-ice-lake-thunderbolt-3-integration/

"Two PCIe controllers go to each of the CIOs. Previously, there was just a single PCIe controller going to the Titan Ridge controller, so there was effectively one PCIe controller for both ports. This means that compared to the prior generation, each port now effectively has double the bandwidth."

I'm quite happy that Intel listened users inputs for once, integrating its solution for the best of consumers and industry requirement.
