Please describe the expected behavior?

I would expect to be able to override this in the appsettings.json, e.g. as follows:

"WriteTo": [ { "Name": "Elasticsearch", "Args": { "nodeUris": "https://localhost:9200/", "indexFormat": "myapp-dev-{0:yyyy.MM}", "autoRegisterTemplate": true, "autoRegisterTemplateVersion": "ESv7", "minimumLogEventLevel": "Information", "connectionGlobalHeaders": "Authorization=Basic XXXXXXXXXXX==", "connectionTimeout": 5, "emitEventFailure": "WriteToSelfLog", "ignoreCertificateErrors": true } } ]
