Using the customCloudProvider serviceoverride works with this config:

cloud_provider:
  name: aws
  customCloudProvider: |-
    [serviceoverride "ap-southeast-2"]
    URL = https://ec2.ap-southeast-2.amazonaws.com/
    SigningRegion = custom-signing-region
    Service = ec2
    Region = ap-southeast-2

@ryanelliottsmith I'm curious, did you go back and verify it wasn't a formatting issue? Your original post used different YAML formatting which I think results in different key/values being presented to K8s. Your follow-up comment is formatted the way I would expect.

The Amazon EC2 (in-tree) provider using awsCloudProvider has the Go structs to handle the service overrides so I would expect it to work.
