"Decouple X from Y" vs "Decouple X with Y" vs "Decouple X and Y"
A database or CS-related stack exchange would likely be your best place to ask this for industry-specific usage, but from a technical writing perspective there are nuanced differences.
"Decouple X from Y" implies X can be freely modified, and changes to Y should be very limited in scope.
"Decouple X and Y" implies that both are open for modification to ensure decoupling.
"Decouple X with Y" is not idiomatic and I have never seen it used.
For your purposes, you may want to say "and" if the scope of changes are rhetoric or unknown.
