Autofac unregisters all interface implementations

Question

Can I unregister all interface implementations in Autofac?

My scenario:

I am registering two modules, one DefaultModule and later a SpecificModule, if some conditions are met.

builder.RegisterModule(new DefaultModule());

if (someCondition)
{
   builder.RegisterModule(new SpecificModule());
}

Two modules register several named instances of the interface, let me call it ISomething.

Inside the Load function in DefaultModule:

builder.RegisterType<DefaultSomething1>().Named<ISomething>("DefaultSomething1").SingleInstance();
builder.RegisterType<DefaultSomething2>().Named<ISomething>("DefaultSomething2").SingleInstance();

Inside the load function in the SpecificModule:

builder.RegisterType<SpecificSomething1>().Named<ISomething>("SpecificSomething1").SingleInstance();
builder.RegisterType<SpecificSomething2>().Named<ISomething>("SpecificSomething2").SingleInstance();

When I register a SpecificModule, I want to undo all previous ISomething registrations, since they are being entered as a collection into another constructor.

public SomeClass(IEnumerable<ISomething> somethingCollection)
{
   _somethingCollection = somethingCollection;
}

Is it possible? Or is it better to do it differently?
