Answer 1

Lambda Limit is 512 Mb Lambda Limits, and cannot be changed.

The following quotas apply to function configuration, deployments, and execution. They cannot be changed.

/tmp directory storage 512 MB

If you need to run task that needs more space, one option would be convert the lambda to a container and run it as a fargate task.

The limits for fargate are 200Gb Fargate Tasks storage information

By default, Amazon ECS tasks hosted on Fargate using platform version 1.4.0 or later receive a minimum of 20 GiB of ephemeral storage. The total amount of ephemeral storage can be increased, up to a maximum of 200 GiB, by specifying the ephemeralStorage parameter in your task definition.

You could also setup EFS for lambda to have virtual unlimited space which can also be shared with other services, such as EC2, ECS and other Lambda functions.
