  We propose a model based on the interplay between the type-II seesaw and
scotogenic neutrino mass generation mechanisms. The setup features a
$\mathbb{Z}_8$ discrete flavour symmetry which is broken down to a residual
$\mathbb{Z}_2$ responsible for stabilising dark matter. A singlet scalar field
is introduced to implement spontaneous CP violation. The effective neutrino
mass matrix two-texture zero structure leads to sharp neutrino sector
predictions. We analyse the constraints imposed on the model by current and
future charged lepton flavour violation experiments. This framework provides
two viable dark matter candidates, scalar or fermion. We investigate the scalar
dark matter scenario considering relic density, direct-detection and collider
constraints.
