Remove unnecessary objects from Elastic Common Schema logs

Question

I am using Serilog and Elastic.CommonSchema.Serilog to have console logs with ECS fields in JSON format.

I don't need to have the objects like host, process in the output. How can I remove them?

ENV:

ASP.NET Core 6 / Alpine Linux Container

Code:

Log.Logger = new LoggerConfiguration()
    .MinimumLevel.Is(LogEventLevel.Debug)
    .MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
    .MinimumLevel.Override("Microsoft.Hosting.Lifetime", LogEventLevel.Information)
    .Enrich.FromLogContext()
    .WriteTo.Async(a => a.Console(new EcsTextFormatter()))
    .CreateLogger();

No any Serilog related modifications in appsettings.json

I'm getting below output.
