supports no-op deploys on no change?

if a function hasn't changed, is it possible with func tools and kudu lite to effect a detection of no changes (md5 checksum?) and not perform the update/upload? linux consumption runtime v3.

The request concerns func tools and Kudu Lite for Linux Consumption runtime v3; start by tracing how a deploy determines whether a function changed. Confirm whether an MD5 or equivalent no-change check can happen before the update/upload, and define the expected skipped-deploy behavior.
