Get rid of Generated using the Generated using the NSwag toolchain v11.0.0.0 (Newtonsoft.Json v13.0.0.0)

Question

Im generating c# class from json schema with next code:

var schemaName = Path.GetFileNameWithoutExtension(schemaDestination)
    .Humanize().Pascalize().Replace("Schema", "");

var json = File.ReadAllText(schemaDestination);
var schema = await JsonSchema.FromJsonAsync(json);
schema.Title = $"{schemaName}BusMessage";

var genSettings = new CSharpGeneratorSettings
{
    ClassStyle = CSharpClassStyle.Poco,
    JsonLibrary = CSharpJsonLibrary.SystemTextJson,
    Namespace = $"CourierService.Application.Generated.{schemaName}BusMessage",
    GenerateDataAnnotations = false, // Disable NSwag annotations
    GenerateOptionalPropertiesAsNullable = true, // Optional: To make properties nullable
    GenerateJsonMethods = false, // Disable generation of JSON methods (ToJson, FromJson)
    GenerateNullableReferenceTypes = true, // Optional: To generate nullable reference types
};

var generator = new CSharpGenerator(schema, genSettings, new CSharpTypeResolver(genSettings));

var res = generator.GenerateFile();

 await File.WriteAllTextAsync($"../{destinationDir}/{schemaName}BusMessage.cs", res);

and i get:
