Plugins are loaded into pod memory which is not expected

Iam performing terraform operations in kubernetes pod and it is attached with Persistent Volume. When iam run terraform init/apply entire plugin is getting loaded into memory and memory spike does not come down which is not expected.

But when i delete the pod and tried running the same operations, now plugin not loading into memory and working as expected.

How can i stop loading terraform plugin into pod memory.

Help me to resolve this issue.
