$ aws configure

3.    Take an AMI of the Instance to have as a backup

4.    Install the driver to the instance

5.    Stop the Instance

6.    Change the Instance Type

7.    Run the Describe-Instance Command locally from the AWS CLI –

aws ec2 describe-instances --instance-ids instance-id --query “Reservations[].Instances[].EnaSupport"

8.    Run the Modify-Instance-Attribute Command locally from the AWS CLI –

aws ec2 modify-instance-attribute --instance-id instance-id --ena-support

9.    Run the Describe-Instance Command locally from the AWS CLI again to verify –

aws ec2 describe-instances --instance-ids instance-id --query "Reservations[].Instances[].EnaSupport"

10.  Start the instance and check the networking and sharing center
