I tried the following:

@Binds @IntoMap @ClassKey(UserViewModel::class)
        abstract fun bindUserViewModel(vm: UserViewModel) : UserViewModel

        @Binds @IntoMap @ClassKey(UserViewModel::class)
        abstract fun bindUserViewModel(vm: UserViewModel) : ViewModel

        @Binds @IntoMap @ViewModelKey(UserViewModel::class)
        abstract fun bindUserViewModel(vm: UserViewModel) : UserViewModel

        @Binds @IntoMap @ViewModelKey(UserViewModel::class)
        abstract fun bindUserViewModel(vm: UserViewModel) : ViewModel

where

@MustBeDocumented
@Target(AnnotationTarget.FUNCTION)
@Retention(AnnotationRetention.RUNTIME)
@MapKey
annotation class ViewModelKey(val value: KClass<out ViewModel>)
