Hello @Angus Reid,
I know it is possible to deploy (also list, export, import, and delete) an existing node settings package via UVMS CLI (ex: unidpl PKG <...> -pkgtype SETTINGS <...>). However, I have not yet found a way to create such a package outside of UVC. Once the package is created in UVC, it is definitely possible to deploy it to new nodes. See here for details:
unidpl PKGI know there are a lot of auto-deployment features slated for v7 due early next year, so maybe this functionality will be added in this version. Or perhaps there is another way to accomplish this that someone from Broadcom might know of.
I hope that helps!
