No. Overriding the parameters in the branch is exactly the same thing. We've tried various combination of personal branches and such and it just doesn't work in any reasonable capacity.
I'm asking if there is a way to have ADF Instance specific parameters. As asked, something that works like Configuration/Application settings for an App Service.
At this point, we've pretty much given up, already needing 4 branches to make dev, test, preprod and prod. <- This completely unnecessary complication is due to a lack of instance level parameters.
The only viable solution seems to be re-clone every branch so local parameters aren't overwritten.
