In this contribution, the final measurements of the centrality dependence of the nuclear modification factor (R\rm AA) of non-prompt \rm D0 in Pb--Pb collisions at √s\scriptscriptstyle \rm NN = 5.02 TeV will be presented. These measurements provide important constraints to the in-medium mass dependent of energy loss and hadronisation of the beauty quark. The p\rm T-integrated non-prompt \rm D0 R\rm AA will be presented for the first time and will be compared to the prompt \rm D0 one. This comparison will shed light on possible different shadowing effects between charm and beauty quarks. In addition, the first measurements of non-prompt \rm Ds production in central and semi-central Pb--Pb collisions at √s\scriptscriptstyle \rm NN = 5.02 TeV will be discussed. The non-prompt \rm Ds measurements provide additional information on the production and hadronisation of \rm Bs mesons. Finally, the first measurement of non-prompt D-mesons elliptic flow in Pb--Pb collisions at √s\scriptscriptstyle \rm NN = 5.02 TeV will also be discussed. This measurement can constrain the degree of thermalisation of beauty quarks in the hot and dense QCD medium.
