Hello Muthu,
If you decide not to use Adobe SDK, I suggest you to remove it from Application Code.
But if you are in dilamo or have a plan to turn it on later, you can still keep it in your Application Code and ask developer to turn off the settings related to Adobe SDK so that you wont have issues with Server Calls (Make sure that Server Calls are not firing while you turn off the settings related to Adobe Analytics). Later, you can turn on the settings without SDK push to the customers.
Hope this helps!
Thank You!
