Following ITS realignment the mean vertex position may change.
To avoid recalibration of the huge amount of MeanVertex objects in the CCDB,
one can globally bias them via env.var O2_DPL_MVBIAS providing the
--configKeyValues-like string for the MeanVertexBiasParam
ConfigurableParam ("mvbias"). E.g.

export O2_DPL_MVBIAS="mvbias.xyz[0]=0.002;mvbias.xyz[1]=-0.12;mvbias.slopeY=0.0005"

will shift all loaded positions by 0.002 cm in X and -0.12 cm in y and increase the
y slope by 0.5mrad.
At the very first call of MeanVertex constructor the bias will be reported as:
root [0] o2::dataformats::MeanVertexObject mv;
[INFO] Mean vertex is biased by: XYZ: 0.0020,-0.1200,0.0000 SlopeXY: 0.000e+00,5.000e-04
