Yes! Since the USB-C to USB-C cable is not included in the package of Kamvas 22, you can purchase a full-featured USB-C to USB-C cable from other brands. But please make sure the full-featured USB-C to USB-C cable you purchased at least supports USB3.1 GEN1 data transfer protocol and DP1.2.
For Kamvas 22 Plus, the USB-C to USB-C cable is included. So you do not need to buy a USB-C to USB-C cable again.
