Hi Ethan,

This should be possible using the ContentLanguageSettingRepository (EPiServer.DataAbstraction).

As far as I'm aware, if content inherits language settings from it's parent then it has no ContentLangaugeSetting. So I believe you'd want to do something like this (which I'll caveat by saying I haven't tested at all):

var languageSettings = _contentLanguageSettingRepository.Load(contentLink);

if (languageSettings == null)
{
	return;
}

foreach (var languageSetting in languageSettings)
{
	_contentLanguageSettingRepository.Delete(contentLink, languageSetting.LanguageBranch);
}
