usb c hub

Hello, I plan on using an usb-c dock and will be connecting my monitor to the HDMI 2.0 port on the dock. This link to the laptop is 5GB/s and I am wondering if this holds back the performance of HDMI 2.0 Laptop: Huawei matebook 14 2020 Thank you for your time in advance. Greetings, Sam

I'm looking to get a USB-C hub with displayport/HDMI and USB type C for a Dell Latitude 7490. The USB-C docking ports with charging that Dell sells are expensive, and I was wondering if I could get something like this, and plug the USB C end into the USB C port on the hub?
