It might be possible for you to use your USB C port on your GPU. But it also depends on what you're trying to accomplish.
In this case the cable must provide video signal enough power and carry data. Currently I only know of one GPU that has a USB C port that
might work for this case which is the NVIDIA RTX 2080 series. See this article: https://www.eurogamer.net/digitalfoundry-2019-02-28-psa-the-usb-c-port-on-rtx-graphics-cards-isnt-just-for-vr (archive)
To be clear I have never personally tested this scenario with a 2080 card.
If a USB C port is on a GPU it should definitely support a video signal.
