update-event-source-mapping

• For poll-based sources like SQS, Kinesis, or DynamoDB streams you can disable the lambda by disabling the mapping so Lambda stops pulling messages

# find the UUID
aws lambda list-event-source-mappings --function-name my-function

# disable it - Disable the trigger (event source mapping)
aws lambda update-event-source-mapping \
  --uuid <uuid> \
  --enabled false

• For push-based sources, like EventBridge/CloudWatch Schedule or API Gateway triggers, disable the rule rather than the Lambda

aws events disable-rule --name my-rule
