Updation of ASCP Plan Option Calculate Key Performance Indicator via backend table update?

We are in 12.2.4.1 environment.  Has anybody updated plan options via backend script? 

Basically there are Archive jobs that get kicked off based on a configuration of the plan, not an actual Launch Parameter we could control.  We only need the Archive to run once a day not twice a day when the plan runs.  Hence only way is to have someone manually login every day after plan launches and check or uncheck that configuration or have a backend script do it .  We are just looking at shaving time off of the plan runs as we are up against a window that is getting smaller and only need archival once a day
