Hello community Once we import the resources from aws to pulumi stack ( ex ec2) , and if i want to remove it from pulumi in future ( suppose if i dont want to manage that resource under pulumi) how can we do it?

You can, see https://www.pulumi.com/docs/guides/adopting/import/ about importing existing resources. If you want pulumi to stop tracking a resource you can remove it from your program and delete it from the pulumi state with

pulumi state delete <urn>

see https://www.pulumi.com/docs/reference/cli/pulumi_state_delete/

Thank you 🙏 i will take a look :)
