Perform operation without modifying updated_at field

If you would like to perform model operations without the model having its updated_at timestamp modified, you may operate on the model within a closure given to the withoutTimestamps method.

Available from Laravel 9.31.

$user = User::first();
 
// `updated_at` is not changed...
 
User::withoutTimestamps(
     fn () => $user->update(['reserved_at' => now()])
);
