Disabling custom ordering in config file?

Hi All, have a small question. How to disable custom ordering of properties in config file ?
I want to save properties in same way as i create it (Firstly SettingsB, then SettingsA):

Code:

protected override void LoadDefaultConfig()
{
    var config = new ConfigData
    {
        SettingsB = new Dictionary<string, string>
        {
            {"param1", "true"},
            {"param2", "true"},
            {"param3", "true"}                              
        },
      
        SettingsA = new Dictionary<string, string>
        {
            {"param1", "true"},
            {"param2", "true"}
        }
    }
  
    SaveConfig(config);
}  void SaveConfig(ConfigData config) => Config.WriteObject(config, true);

In config file i have:
SettingsA
SettingsB

 

Yes, i used it, but it didn't help.
As i see, config file was rewritten twice. Firstly with expected values and then with wrong ordered values. So i make this trick and have result i need (even without JsonProperty(Order = xxx) ):

Code:

void SaveConfig(ConfigData config)
{
      timer.Once(0.1f, ()=>Config.WriteObject(config, true));
}
