How to validate a single field?

Is there a ->validateOnly in filament? I want to call it using ->afterStateUpdated()

$livewire->validateOnly()

TextInput::make('student.baptism_year')
                ->label('Baptism Year')
                ->numeric()
                ->integer()
                ->minLength(4)
                ->maxLength(4)
                ->lazy()
                ->afterStateUpdated(function(Livewire $livewire, Closure $get, $state){
                    $livewire->validateOnly('student.baptism_year');
                    
                    if( strlen($state) == 4){
                        $this->autoSaveStudent('baptism_year', $state);
                    }
                }),

TextInput::make('student.baptism_year')
                ->label('Baptism Year')
                ->numeric()
                ->integer()
                ->minLength(4)
                ->maxLength(4)
                ->lazy()
                ->afterStateUpdated(function(Livewire $livewire, Closure $get, $state){
                    $livewire->validateOnly('student.baptism_year');
                    
                    if( strlen($state) == 4){
                        $this->autoSaveStudent('baptism_year', $state);
                    }
                }),

Like this? Cool, I got it. 1. I fixed the instance

use Livewire/Component as Livewire;

use Livewire/Component as Livewire;

2. Apply it in the lifecycle

$livewire->validateOnly('data.student.baptism_year');

$livewire->validateOnly('data.student.baptism_year');

How about for array properties like Repeater? wow, I could just do this:

->afterStateUpdated(function(Livewire $livewire, Closure $get, Component $component, $state){
        $livewire->validateOnly($component->getStatePath());

        $this->autoSaveSibling($get('id'), 'personal_email', $state);
    }),

->afterStateUpdated(function(Livewire $livewire, Closure $get, Component $component, $state){
        $livewire->validateOnly($component->getStatePath());

        $this->autoSaveSibling($get('id'), 'personal_email', $state);
    }),
