How To Update existing stage settings?


I have created a stage ‘v1’ using serverless yaml. Now i want to enable the Cloud Watch Settings. When i am trying to do so using serverless yaml using below code:

MetricsEnabled: true
LoggingLevel: INFO
DataTraceEnabled: true

I am getting below error:
An error occurred: ApiGatewayStageV1 - v1 already exists.

How can I update the settings in an already created stage ‘v1’??
