What can be modified with no rebuild in rapid accelerator mode?

I have a batch simulation I am running setting Constant blocks, From Workspace blocks and data dictionary values via overiding values in data dictionary and model workspace with simIn.setVariable. This works well when but when running rapidAccelerator mode with setModelParameter('RapidAcceleratorUpToDateCheck', "off"); the run doesn't take the values set by setVariable. Do I have to switch these constants and From Workspace blocks to inputs to succesfully run with no rebuild in Rapid Accelerator mode?

In general, if the values of those blocks are defined in variables and they are specified as tunable, then it does not require re-build for rapid accelerator mode. Here is the doc link for R2024a.

Is there a special way in which variables should be specified as tunable? I may have missed something there.
