Original answer:

There isn't a way to disable retry behavior of Lambda functions. I suggest two options to deal with that:

1. Make your Lambda able to handle retry cases correctly. You can use context.AwsRequestId (or corresponding field) that will be the same when a Lambda is retried.
2. Put your Lambda inside a state machine (using AWS Step Functions). You can only then disable retries. This blog post I've written gives a more general explanation.
