Based on the comments.

Since .env is used on local workstation successfully, it can also be used on ec2 instance.

Just have to be careful with not string any sensitive information in .env and using public repositories, as you may leak your passwords or access keys.

For storing secrets at AWS, the recommended way would be through secret manager or ssm parameter store. Also any permissions that your app may require to access these or other AWS services should be provided through instance role, not by hard codding AWS credentials into app or instance.
