                      renormalization scheme from the comparison of theoretical
                      predictions for $pp \rightarrow t\bar{t} + X$ at
                      next-to-next-to-leading order (NNLO) QCD accuracy with
                      experimental data collected by the ATLAS and CMS
                      collaborations for absolute total, normalized
                      single-differential and double-differential cross-sections
                      during Run 1, Run 2 and the ongoing Run 3 at the Large
                      Hadron Collider (LHC). For the theory computations of
                      heavy-quark pair-production we use the MATRIX framework,
                      interfaced to PineAPPL for the generation of grids of theory
                      predictions, which can be efficiently used a-posteriori
                      during the fit, performed within xFitter. We take several
                      state-of-the-art parton distribution functions (PDFs) as
                      input for the fit and evaluate their associated
                      uncertainties, as well as the uncertainties arising from
                      renormalization and factorization scale variation. Fit
                      uncertainties related to the datasets are also part of the
                      extracted uncertainty of the top-quark mass and turn out to
                      be of similar size as the combined scale and PDF
                      uncertainty. Fit results from different PDF sets agree among
                      each other within 1$\sigma$ uncertainty, whereas some
                      datasets related to $t\bar{t}$ decay in different channels
                      (dileptonic vs. semileptonic) point towards top-quark mass
                      values in slight tension among each other, although still
                      compatible within $2.5 \sigma$ accuracy. Our results are
                      compatible with the PDG 2022 top-quark pole-mass value. Our
                      work opens the road towards more complex simultaneous NNLO
                      fits of PDFs, the strong coupling $\alpha_s(M_Z)$ and the
                      top-quark mass, using the currently most precise
                      experimental data on $t\bar{t} + X$ total and
                      multi-differential cross-sections from the LHC.},
