I'm using Pulumi Python SDK to deploy an EC2 instance with one security group attached. If I attach additional security group to that same instance, Pulumi terminates previously create EC2 instance and deploys a new instance with 2 security groups.
Is it possible to avoid EC2 instance termination and instruct Pulumi to simply attach additional security group to existing instance?

without seeing the exact code it's hard to say, but you should be using the
```NetworkInterfaceSecurityGroupAttachment```
class to attach additional sg's after the interface / ec2 instance is created
