AWS SNS connector with other provider (Scaleway)

I need to use the SNS connector with the provider Scaleway.
The AWS SNS Connector send HTTP requests to http://sns.{region}.amazonaws.com
Scaleway expects this url https://sns.mnq.{region}.scaleway.com
As it is implemented in the AWS SQS Connector, is it possible to specify the url of the SNS service ?
Thanks for your help
