  We study marginal deformations of a class of three-dimensional
$\mathcal{N}=2$ SCFTs that admit a holographic dual description in massive type
IIA supergravity. We compute the dimension of the conformal manifold in these
SCFTs and identify a special submanifold with enhanced flavor symmetry. We show
how to apply the TsT transformation of Lunin-Maldacena to construct explicit
supersymmetric AdS$_4$ solutions of massive type IIA supergravity with
non-trivial internal fluxes that are the holographic dual of these marginal
deformations. Finally, we also briefly comment on a class of RG flows between
some of these SCFTs that also admit a holographic realization.
