Amazon EC2 T instances now support Unlimited Mode at AWS account level

Starting today, Amazon EC2 is introducing the ability for customers to choose an Unlimited mode preference using CLI and SDK at the account level for T3, T3a, and T2 instance types. The new API will enable customers to perform a one time action of setting Unlimited or Standard mode as the default preference for all T3, T3a, and T2 instance launches.
