Updating a config file parameter on a RT target

[ELDMATT]

I have an RT target running a Real-Time Application that was built a number of years back (2017 LabVIEW).  The deployed build included a .ini file containing a value that is read during the target startup initialization through the VI that was set to run automatically upon startup.  I need to update this value and was wondering if it is necessary to re-build and re-deploy the application to the target after updating the .ini file value locally?  Is there a way to just keep the same build running but push the new value to the .ini file on the RT target?

You can deploy only the INI file.

The deployment from LabVIEW ADE is essentially just file transfer and some INI modification. See Deploying a LabVIEW Real-Time Startup Executable Without the LabVIEW Development Environment for details.
