How to delete a record that has a relationship – Laravel

I want to delete a record that has a foreign key from another table, but at the time of performing the action it leaves me by some restriction. I would like to know if there is a way to delete it without deleting the other record that is related.

public function destroy($id) {
        try {
            $exists = Orderdetail::where('id', $id)->exists();
            if (!$exists) {
                return response()->json(
                    [
                        'message' => 'Error al eliminar la orden',
                        'status'  => 'error',
                        'data'    => 'La orden por este id no existe',

                    ], 500
                );
            }

            // eliminar la orden
            $order = Orderdetail::findOrFail($id);
            $order->delete();


        } catch (Throwable $th) {
            return response()->json(
                [
                    'message' => 'Error al eliminar la orden',
                    'status'  => 'error',
                    'data'    => $th->getMessage(),

                ], 500
            );
        }
    }
