Thanks for posting your question in the Microsoft Q&A forum.
You generally do not need to update TLS settings specifically in the Azure DevOps service connection.
Azure DevOps Services has already deprecated support for TLS 1.0 and 1.1, enforcing TLS 1.2 for all connections. this change was implemented at the service level, not at the individual connection level
The TLS settings you updated in the Azure portal are likely for specific Azure resources (like App Services or Azure Functions) and are separate from Azure DevOps configurations.
