Yes! Since the USB-C-to-USB-C cable is not included with the Kamvas 22 package, 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 full-featured USB-C-to-USB-C cable is included. So you do not need to buy another USB-C-to-USB-C cable.
