Please be more accurate about your problem and setup.
I’m not sure about your actual problem, but here are some points which might help you:
SonarQube does not care about tslint.json, and property sonar.ts.tslint.configPath belongs to a community plugin https://github.com/Pablissimo/SonarTsPlugin (I don’t know if you installed it)
You can disable SonarQube rules through profiles page.
