Model::preventLazyLoading doesn't do anything

Description

public function boot(): void
{
Model::preventLazyLoading(true);
}

Turning this setting on doesn't do anything. The model is still "lazy loaded". Please fix it

Steps To Reproduce

Add Model::preventLazyLoading(true)

Try to lazy load anything and it won't throw the exception:

> Model::preventLazyLoading(true)
> Message::find(34)->sender
[!] Aliasing 'Message' to 'App\Models\Message' for this Tinker session.
= App\Models\User {#7749
    id: 25,
    ...

Adding a line in Concerns/HasAttributes.php:534 shows that this setting isn't respected:

= App\Models\Message {#7744
    id: 34,
    ...
  }

> Message::find(34)->sender
false // vendor/laravel/framework/src/Illuminate/Database/Eloquent/Concerns/HasAttributes.php:534
```php 
// inside Concerns/HasAttributes.php:534
dd($this->preventsLazyLoading);
        if ($this->preventsLazyLoading) {
            $this->handleLazyLoadingViolation($key);
        }

Solved it in a temporary way by doing this:

<?php

namespace App\Models\Base;

class Model extends \Illuminate\Database\Eloquent\Model
{
    public function __construct(array $attributes = [])
    {
        parent::__construct($attributes);
        $this->preventsLazyLoading = \Illuminate\Database\Eloquent\Model::preventsLazyLoading();
    }
}


class MyModel extends Model {}

Then it works...

> Message::find(34)->sender
   Illuminate\Database\LazyLoadingViolationException  Attempted to lazy load [sender] on model [App\Models\Message] but lazy loading is disabled.

I think the framework should handle this case though, as this setting is mentioned in the documentation.

I believe this behaviour is intended (or relaxed). If you have a singular model or relation that is lazy loaded, it won't throw LazyLoadingViolationException because no N+1 relation query is created.

It will only throw if the relation is more than one.

See the above. Thanks @Rizky92
