I've almost always gotten everything I want from security teams over my career. Usually a quick and honest chat with them gets you pretty far. I always lead with some flavor of "In my perfect world, I have 100% access and ability to everything, everywhere all the time. In your perfect world, I don't even have a computer. Here's why I need X permission / Y user group / z application"

From the perspective of big corporate security - developers are a wild nuisance who file the lions share of the tickets and soak up an inordinate amount of resources. Being able to at least explain to them that you understand their objectives and are not overrequesting just for the sake of overrequesting goes a long way.
