Do I need Xcode 12 to add network privacy prompt plist string?

Do I need Xcode 12 to add network privacy prompt plist string? Can I add it using Xcode 11 and release binary with it there ahead of time laying dormant / ahead of officially having our app supporting iOS 14?
Hello, I tried to provide NSLocalNetworkUsageDescription already in Xcode11.6 and it was displayed by iOS14.
Thanks!
