I'm using Kodi (osmc) and am running into some issues with the hdmi-switch it's connected to. In order for the switch to auto-change the port, I need some easy way of toggling hdmi off/onn, essentially making Kodi force a handshake and changing the port.

Thoughts, anyone?

None, unless you at least provide info about your hardware.
OSMC runs on different boards where HDMI stuff is implemented in different ways.
However your question is better asked on https://discourse.osmc.tv/

Basically you want to use 'tvservice' command with appropriate switches.
You may need to restart Kodi.
