Can we delete instance user-data from EC2 instance's meta-data in Cloudformation

Question

We can get the userdata by this command:

http://169.254.169.254/latest/user-data

But is there a way to delete this from instance itself?

I know we can delete userdata by stopping it, but rather than doing that, can we delete it from within the instance itself?

从AWS CLI调用modify-instance-attribute命令。

aws ec2 modify-instance-attribute --instance-id <your-instance-id> --user-data ":"
