For real-time validation, you can try something like this:

Repeater::make('repeater')
    ->schema([
        Select::make('select')
            ->options([
                1 => 'Option 1',
                2 => 'Option 2',
                3 => 'Option 3',
            ])
            ->reactive()
            ->afterStateUpdated(function ($component, $state, $livewire) {

                $items = $component->getContainer()->getParentComponent()->getOldState();
                $livewire->resetErrorBag($component->getStatePath());
                
                if (in_array([$component->getName() => $state], $items)) {
                    $livewire->addError($component->getStatePath(), 'duplicated');
                }
            })
    ])

Repeater::make('repeater')
    ->schema([
        Select::make('select')
            ->options([
                1 => 'Option 1',
                2 => 'Option 2',
                3 => 'Option 3',
            ])
            ->reactive()
            ->afterStateUpdated(function ($component, $state, $livewire) {

                $items = $component->getContainer()->getParentComponent()->getOldState();
                $livewire->resetErrorBag($component->getStatePath());
                
                if (in_array([$component->getName() => $state], $items)) {
                    $livewire->addError($component->getStatePath(), 'duplicated');
                }
            })
    ])

To prevent duplicate data, you can use hooks: https://filamentphp.com/docs/2.x/admin/resources/creating-records#lifecycle-hooks

What I was interested about is to filter items in Select Field so when an item is selected it will be removed from the list in Repeater items below.
