Elastic APM .Net : How to override appsettings.json

Kibana version: 7.10.1

Elasticsearch version: 7.10.1

APM Server version: 7.10.1

APM Agent language and version: .net Agent (Latest)

I've a asp .net core application with multiple environment (Staging, Integration, QA) . each environment have his specific configuration

I would specify the elastic apm server @iP , only in QA env. without putting them in appsettings.json

Thanks
