How to disable StyleCop Plus rule SP2001 "Only tab characters are allowed to be used for indentation"

Question

I have added a nuget package StyleCopPlus.MSBuild https://www.nuget.org/packages/StyleCopPlus.MSBuild/4.7.49.5

which comes with Settings.StyleCop that I can copy to solution folder and modify, but I'm getting warning SP2001 "Only tab characters are allowed to be used for indentation" but I can't find a rule to disable it.
