We investigate the effects of (2+1)d event-by-event fluctuating hydrodynamic backgrounds on the nuclear modification factor and momentum anisotropies of heavy-flavor mesons. Using the state-of-the-art D and B mesons modular simulation code (the so-called DAB-mod), updated recently with heavy-light quark coalescence, we perform a systematic comparison of different transport equations, including two energy loss models and a relativistic Langevin model with two drag parametrizations. We present the resulting D0 meson RAA, v2 and v3, using the multiparticle cumulant method, in Pb-Pb collisions at $$\sqrt{s_{\rm NN}}=5.02$$ and compare them to the latest experimental data. We investigate the $$v_2\{4\}/v_2\{2\}$$ ratio as a function of centrality for different initial conditions (MCKLN vs. Trento) and different system geometries and sizes (coming from Pb-Pb collisions at $$\sqrt{s_{\rm NN}}=5.02$$, spherical and prolate Xe-Xe collisions at $$\sqrt{s_{\rm NN}}=5.44$$ TeV).
