abstract = {We report on the first calibration of the standard Belle II
$B$-flavor tagger using the full data set collected at the
$\Upsilon(4{\rm S})$ resonance in 2019 with the Belle II
detector at the SuperKEKB collider, corresponding to 8.7
fb$^{-1}$ of integrated luminosity. The calibration is
performed by reconstructing various hadronic charmed
$B$-meson decays with flavor-specific final states. We use
simulation to optimize our event selection criteria and to
train the flavor tagging algorithm. We determine the tagging
efficiency and the fraction of wrongly identified tag-side
$B$~candidates from a measurement of the time-integrated
$B^0-\overline{B}^0$ mixing probability. The total effective
efficiency is measured to be $\varepsilon_{\rm eff} =
\big(33.8 \pm 3.6(\text{stat}) \pm 1.6(\text{sys})\big)\\%$,
which is in good agreement with the predictions from
simulation and comparable with the best one obtained by the
Belle experiment. The results show a good understanding of
the detector performance and offer a basis for future
calibrations.},
