public function items3() {
return $this->hasMany(Item3::class);
}
public function items4() {
return $this->hasOne(Item4::class);
}
}
$events = Event::all();

Answer 1

If you have a single instance of a model object, you can do:
$obj->withoutRelations();

Answer 2

As laravel documentations says you can use without: https://laravel.com/docs/8.x/eloquent-relationships
Model
protected $with = ['item1','item2','item3','item4'];
Controller
$events = Event::without(['item1','item2','item3','item4'])->get();

Answer 3

I met this problem one day, and it turned out that I was using relation in scope method. Because of this relation values were added to response.
Check out this example:
class Event extends Model {
public function items() {
return $this->hasMany(Item::class);
}
[...]
public function scopeItemsGreen() {
return $this->items->every(function ($item) {
return $item->color == 'green';
});
}
