<p dir="ltr">There is an evidence for significant evolution in the gaseous and dust properties of galaxies since the era of cosmic noon (1 < z < 2.5). It is also well known that supermassive black holes co-evolve with their host galaxies, suggesting a constant connection between the small-scale (nuclear) and large-scale regions of galaxies. A fundamental component of Active Galactic Nuclei (AGN) is the "torus", a dense, dusty structure that acts as the interface between the accretion disc and the ISM of the host galaxy. One may speculate that the transitional nature of the torus makes it a prime subject to search for evolution since cosmic noon. In this work, we use <i>JWST</i> high resolution near- and mid-IR imaging from the CEERS survey to disentangle the emission from the torus in unprecedented detail for 88 X-ray selected AGN at z ~ 2. Combining low-resolution multi-band photometry at UV to FIR wavelengths, from the archival CANDELS and HELP surveys, with the high-resolution <i>JWST</i> photometry, we employ a novel SED fitting method to constrain essential AGN and torus parameters, such as accretion disc luminosity, torus opening angle, and inclination angle. Despite the well-known evolution of the ISM and structural properties of AGN hosts to these redshifts, our population-level analysis finds no clear evidence for the evolution of the torus when compared to similar local AGN.</p><p dir="ltr">This dataset provides the posterior distributions of 14 galaxy and AGN parameters and 1 derived AGN paramter for all 88 sources in our sample. These posterior distributions were obtained by SED fitting as described in the accompanying paper.</p>
