Can you just set scanning to passive? - I know that depends on how the
processing is triggered, so it may not work in your case.

The setup is working fine but with a strange behavior (which might be expected). Writing anything to DISA does not take effect until the PV is processed, so I had to make another fanout record only to process those PVs whenever the calcout record is processed (FLNK). Now assume if the condition is met and the PVs got disabled, if you write anything to the PV, it will not process it but on the next change from calcout. This can be problematic in certain setups. Is there any way to avoid writing at all when the PV is disabled? Or a better way to disable PVs? Thanks.
