How to load the i2c-dev and driver i2c-piix4 for OpenRGB?

I’d like to use OpenRGB to control some keyboard settings. It comes as an AppImage and requires i2c-dev and the driver i2c-piix4 to be loaded.

I installed i2c-tools which provides the above dependencies but nothing gets loaded.

I checked online but e.g. the configuration files to which settings should be added according to the online posts don’t exist on AlmaLinux9.1.

Where/How can I load i2c-dev and the driver i2c-piix4?
