That would be cphSetInstForceDescend. You'd need to have an open physConfig (e.g. using cphFindOpenConfig or cphOpenConfig). There are also APIs to set force descend on cells and occurrences too. Search for any function that begins with "cph" in cdsFinder and then you can hit the "More Info" button (in IC617/ICADV122 onwards) to take you to the full documentation for the function.
