Enable or disable Serilog configuration based on condition

I have the following configuration for Serilog. As you can see below, there are 3 sinks registered for Serilog. I want to enable or disable any specific sink based on a condition. Is it possible to do that in Serilog?

Example For on-premises application, I want to disable AppInsights sink and for a cloud application I want to disable EventLog sink. Could anyone please help me with this?

Serilog Configuration

`

"Serilog": {
     "Enrich": [ "FromLogContext" ],

"MinimumLevel": {
  "Default": "Debug",
  "Override": {
    "Microsoft": "Information"
  }
},

"Using": [ "Serilog.Sinks.ApplicationInsights", "Serilog.Sinks.EventLog", "Serilog.Sinks.File"  ],

"WriteTo": [
  {
    "Name": "ApplicationInsights",
    "Args": {
      "InstrumentationKey": "02FD2F33-C643-4A6A-8DF6-C980C87B7E1F",
      "restrictedToMinimumLevel": "Information",
      "telemetryConverter": "Serilog.Sinks.ApplicationInsights.Sinks.ApplicationInsights.TelemetryConverters.TraceTelemetryConverter,Serilog.Sinks.ApplicationInsights"
    }
  },
  {
    "Name": "File",
    "Args": {
      "path": "log.txt",
      "rollingInterval": "Day"
    }

  },
  {
    "Name": "EventLog",
    "Enabled": false,
    "Args": {
      "manageEventSource": true,
      "restrictedToMinimumLevel": "Error",
      "source": "KiranKumar",
      "logName": "Serilog"
    }
  }
]
      }`

Serilog Version: 2.9.0 .netCore Version: 3.1

I have the same issue here. My assumption is that I can remove one of the sinks from the “Using” to disable it, even though the"WriteTo" still exists. Is this a misunderstanding of the “Using” section?

@rebeccapowell Using works mostly to provide hints on which assemblies Serilog needs to load before the other parts of configuration will become available - it won’t be a reliable way to conditionally turn sinks on/off, unfortunately.
