Serverless-1.0.0 enables deploying an API to be accessible via a AWS API Gateway with a custom domain
The question: With my serverless.yml I need to disable CloudFront's caching (e.g. by setting some zero TTL for caching headers... is there any other way?)
Can that be done from within serverless.yml or serverless framework?

On your custom origin web server application, add Cache-Control no-cache, no-store, or private directives to the objects that you don't want CloudFront to cache. Or, add Expires directives to the objects that you don't want CloudFront to cache.
If you want OPTIONS responses to be cached, do the following: Choose the options for default cache behavior settings that enable caching for OPTIONS responses. Configure CloudFront to forward the following headers: Origin , Access-Control-Request-Headers , and Access-Control-Request-Method .
Open the CloudFront console at https://console.aws.amazon.com/cloudfront/v3/home . Choose Create distribution. In the Cache key and origin requests section, make sure that Cache policy and origin request policy is chosen. For Cache policy, choose the cache policy to attach to this distribution's default cache behavior.
CloudFront allows Serverless applications to provide a fast and low-latency experience to end users by making sure that the static parts of their application load fast, irrespective of where its users are.
Have you tried defining a cachePolicy under provider, as per Serverless's reference YML, and then linking the cachePolicy via a function's CloudFront event? Straight from Serverless Frameworks sample YML like this:
provider:
cloudFront:
myCachePolicy1: # used as a reference in function.events[].cloudfront.cachePolicy.name
DefaultTTL: 60
MinTTL: 30
MaxTTL: 3600
Comment: my brand new cloudfront cache policy # optional
