  Strong cosmic censorship conjecture is central to the deterministic nature of
general relativity, since it asserts that given any generic initial data on a
spacelike hypersurface, the future can be uniquely predicted. However, recently
it has been found that for charged black holes in asymptotically de Sitter
spacetimes, the metric and massless scalar fields can be extended beyond the
Cauchy horizon. This spells doom on the strong cosmic censorship conjecture,
which prohibits precisely this scenario. In this work we try to understand the
genericness of the above situation by studying the effect of NUT charge and
conformally coupled scalar field on the violation of strong cosmic censorship
conjecture for charged asymptotically de Sitter black holes. We have shown that
even in the presence of the NUT charge and a conformally coupled scalar field
strong cosmic censorship conjecture in indeed violated for such black holes
with Cauchy horizon. Moreover, the presence of conformal coupling makes the
situation even worse, in the sense that the scalar field is extendible across
the Cauchy horizon as a $C^{1}$ function. On the other hand, the strong cosmic
censorship conjecture is respected for conformally coupled scalar field in
rotating black hole spacetimes with NUT charge. This reinforces the belief that
possibly for astrophysical black holes, strong cosmic censorship conjecture is
respected, irrespective of the nature of the scalar field.
