  We study a periodically driven central site coupled to a disordered
environment. In comparison to the static model, transport features are either
enhanced or reduced, depending on the frequency of the drive. We demonstrate
this by analyzing the statistics of quasienergies and the logarithmic
entanglement growth between bipartitions, which show similar features: For
frequencies larger than disorder strength, localization is enhanced due to a
reduced effective coupling to the central site. Remarkably, localization can
even be increased up to almost perfect freezing at particular frequencies, at
which the central site decouples due to the emergence of `dark Floquet states'.
This high-frequency domain of our model is bounded by a critical frequency
$\omega_c$, where transport increases abruptly. We demonstrate that $\omega_c$
is determined by one-photon resonances, which connect states across the
mobility edge. This sensitive frequency dependence allows us to fine tune
transport properties of the driven central site model, by unprecented
precision.
