A search for new heavy scalars with flavour-violating decays in final stateswith multiple leptons and $b$-tagged jets is presented. The results areinterpreted in terms of a general two-Higgs-doublet model involving anadditional scalar with couplings to the top-quark and the three up-type quarks($\rho_{tt}$, $\rho_{tc}$, and $\rho_{tu}$). The targeted signals lead to finalstates with either a same-sign top-quark pair, three top-quarks, or fourtop-quarks. The search is based on a data sample of proton-proton collisions at$\sqrt{s}=13$ TeV recorded with the ATLAS detector during Run 2 of the LargeHadron Collider, corresponding to an integrated luminosity of 139f b$^{-1}$.Events are categorised depending on the multiplicity of light charged leptons(electrons or muons), total lepton charge, and a deep-neural-network-basedcategorisation to enhance the purity of each of the signals. Masses of anadditional scalar boson $m_{H}$ between $200-630$ GeV with couplings$\rho_{tt}=0.4$, $\rho_{tc}=0.2$, and $\rho_{tu}=0.2$ are excluded at 95%confidence level. Additional interpretations are provided in models of$R$-parity violating supersymmetry, motivated by the recent flavour and$(g-2)_\mu$ anomalies.
