Laravel provides developers with an easy way to disable primary key and auto-increment features in a model. This is done by setting the $incrementing and $keyType properties in the model.

<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
protected $primaryKey = 'user_id';
public $incrementing = false;
protected $keyType = 'string';
// rest of the model code
}
In this example, To define a User model that has a primary key column named user_id. And disable the auto-increment feature by setting the $incrementing property to false. Also set the $keyType property to 'string' to indicate that the primary key column is of type string.
By setting these properties in the model, Laravel will no longer assume that the model has an auto-incremented primary key column. Instead, it will use the column specified in the $primaryKey property as the primary key.
