Want to disable SES service for my account?

Hello,

You cannot disable a service per say. What you can do is simply deny access to SES (or not grant permissions to use it, a user by default does not have any permission if you don't explicitly grant it with a policy).

You can also use SCPs (Service Control Policies) in order to deny access to a service at the Org/OU or account levels, using an SCP like:

{    
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "DenyAllSesActions",
      "Effect": "Deny",
      "Action": "ses:*",
      "Resource": "*"
    }
  ]
}
