Sure. You can do it 2 ways. System wide with enviroment variable name OCIO or just Houdini enviroment variable.

Attaching image of windows env variable, you just basically need to add/set OCIO and point do the config file.

Second option is just Houdini, that can be done for example with package files, see official docs on what they are https://www.sidefx.com/docs/houdini/ref/plugins.html

Basicaly with packages file you can load config per json file copied in your \Documents\houdini17.5\packages .
Attaching my example file. Just edit the path in json file to where you have your OCIO config. Then save the file to \Documents\houdini17.5\packages\Ocio.json

Sorry for ziping the json, forum does not allow attaching of .json files

Good luck!
