ランタイムでAnalyticsを無効化する（シーン内のオブジェクトにアタッチする必要はない）

DisableAnalytics.cs

using UnityEngine;

public class DisableAnalytics : MonoBehaviour
{
    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
    public static void OnRuntimeMethodLoad()
    {
        UnityEngine.Analytics.Analytics.enabled = false;
        UnityEngine.Analytics.Analytics.deviceStatsEnabled = false;
        UnityEngine.Analytics.Analytics.limitUserTracking = true;
        UnityEngine.Analytics.Analytics.initializeOnStartup = false;
        UnityEngine.Analytics.PerformanceReporting.enabled = false;
    }
}
