Hello. Yes homogeneous Neumann BC are automatically taken into account if nothing is specified. This is related to the variational formulation of the finite element method.
Nevertheless, be careful. In some situation the PDE formulation does not ensure the use of the correct variational formula (this is the case for instance of elasticity system). So, it can be better to use the variational formulation which gives you more control on the way your problem is discretized.
