The $\RAA$ of non-prompt $\Ds$ mesons divided by the one of prompt $\Ds$ mesons (left panel) and non-prompt $\Dzero$ mesons (right panel) for the 0--10% and 30--50% centrality intervals in Pb--Pb collisions at $\sqrtsNN=5.02 \TeV$. The measurements are compared with TAMU model predictions . Statistical (bars) and systematic (boxes) uncertainties are shown.
