As Pascal notes in the linked post

@Customize Severity or Disable some of roslyn warnings on sonar cloud?

You can configure Roslyn analyzers in your project using .editorconfig files: Configure code analysis rules - .NET | Microsoft Docs

These changes will be reflected in what issues are raised and uploaded to SonarQube.
