<p>I would start with turbo_eels.x code of TDDFT module that is
distributed with QE. Of course you have to cautious while dealing
with a 2D system (i.e. check convergence w.r.t to vacuum and etc)
but in principle you can obtain momentum-dependent dielectric
function.</p>

I doubt if you can obtain this from QE or not. The plot is
essentially the -Im\epsilon_Q{\omega}^{-1}. You can have a look
at the Yambo tutail for computing this object from QE DFT
calculations.</div>

Yambo is a FORTRAN/C code for Many-Body calculations
in solid state and molecular physics. Yambo relies on
the Kohn-Sham wavefunctions generated by two DFT
public codes: abinit, and PWscf.The code was
originally developed in the Condensed Matter
Theoretical Group of the Physics Department at the
University of Rome "Tor Vergata" by Andrea Marini. ...</div>
