In these proceedings, we present the second order (ν2) and the third order (ν3) azimuthal anisotropy measurements of strange and multi-strange hadrons such as KS0, Λ, Λ¯, ϕ, Ξ−, Ξ¯+, Ω−, Ω¯+ in Au+Au collisions at √SNN = 27 and 54.4 GeV at STAR. The centrality dependence of ν2 and ν3 as well as the number of constituent quark scaling (NCQ scaling) for all the particles mentioned above are discussed. The ratio of ν2 of ϕ mesons to that of p¯ is presented at √SNN = 54.4 GeV which gives a hint of mass ordering violation at low pT.
