We're playing with the clusterio-mod and it seems we are unable to disable auto-launch for this mod. The checkbox is disabled so the checkmark cant be removed. Is there a way to disable the setting somehow?

Its a startup setting, so you need to change it from the main menu

How do you change it on a dedicated server?
I've tried copying over the mod-settings.dat from local with auto launch off to the server, overwriting the existing mod-settings.dat and starting the server but it had no effect.
The mod was installed on an existing map and there was no option to change this setting at this point.
