It is possible to opt-out of the check for configuration-files by using the CakeContribGuidelinesOmitRecommendedConfigFile setting
and setting it's Include to the file name that should not be checked:
<ItemGroup>
<CakeContribGuidelinesOmitRecommendedConfigFile Include="stylecop.json" />
<CakeContribGuidelinesOmitRecommendedConfigFile Include=".editorconfig" />
</ItemGroup>
