How to use GeneratorNewProjectWizardBuilderAdapter for Project create only, not Module?

I've created own project generator based on GeneratorNewProjectWizard and registered in New Project/Module dialog using  GeneratorNewProjectWizardBuilderAdapter. Works great for creating new projects but there are some glitches while creating module.

How to hide my generator from New Module dialog?

I've tried

override fun canCreateModule(): Boolean {
    return false
}

but it does not affect menu item visibility
