DDC/CI support on Linux

I’d like to know if there is a way to support DDC/CI on Linux?

  • Linux distribution based sur Debian 9.12, Kernel version 4.9.0-12-amd64

  • Drivers Nvidia 430.50

  • We are using the display port connector on both Graphic card and monitor

I haven’t succeeded yet.
Can someone please help me?
