You can also use the [NonSerialized] attribute

[Serializable]
public struct MySerializableStruct
{
    [NonSerialized]
    public string hiddenField;
    public string normalField;
}

From the MS docs:

Indicates that a field of a serializable class should not be serialized. This class cannot be inherited.

If you're using Unity for example (this isn't only for Unity) then this works with UnityEngine.JsonUtility

using UnityEngine;

MySerializableStruct mss = new MySerializableStruct 
{ 
    hiddenField = "foo", 
    normalField = "bar" 
};
Debug.Log(JsonUtility.ToJson(mss)); // result: {"normalField":"bar"}
