Using

IServiceCollection.ConfigureWritable(IConfigurationSection section, string settingsFile = "appsettings.json", bool reloadAfterWrite = false)

section - your configuration section

settingsFile - default appsettings.json

    "MySettings": {
        "MyOption": "MyValue"
    }
}

Startup.cs:

public void ConfigureServices(IServiceCollection services)
{
    services
        .AddOptions()
        .ConfigureWritable<MyOptions>(Configuration.GetSection(nameof(MySettings)));
}

Controllers/MyController.cs:

[Controller]
public class MyController : Controller {
    private readonly IOptionsWritable<MyOptions> _myOptionsAccessor;

    public TeamsController(IOptionsWritable<MyOptions> myOptionsAccessor) {
        _myOptionsAccessor = myOptionsAccessor;
    }

    [HttpPut]
    public IActionResult SetMyOptionValue(string value) {
        _myOptionsAccessor.Update(options => options.MyOptions = value);
    }
}
