be able to automate changes from commande line in a DXP

Context:

Spotfire Cloud, No VPN feature that allow to securely connect to a DB.

So I have to use SDBF file in my DXP.

When I want to promote DXP from UAT to PROD, I have to manually edit all datasource just to change  path.

I also add links in my DXP, the links obviously requires a host and port that changes between UAT & PROD.

i didn't find a way to use a property ${propertyName} do not work.

I can't use IronPython as it's not active in cloud env. (we should have IronPython with a restricted API)

So it would be nice to have a standalone tool that run on linux and windows (ie a java tooling, no dependency on Spotfire Server or Automation Service) that allows to update SDBF file path and properties (if we could use property when defining an URL)
