To remove mention of “IdeoSpaceBehavior” you could run the following 2 lines of JavaScript (write in your own paragraph style name instead of “para-name”):
var myParagraphStyle = app.activeDocument.paragraphStyles.itemByName("para-name");
myParagraphStyle.treatIdeographicSpaceAsSpace = true;
Adding the following line will set diacritic position to “None”, but unfortunately doesn’t remove all mention of it from Style Settings:
myParagraphStyle.diacriticPosition = DiacriticPositionOptions.DEFAULT_POSITION;
I’m guessing that adding the following lines will probably remove mention of Mijokumi and Kinsoku, if they’re present in Style Settings:
myParagraphStyle.mojikumi = MojikumiTableDefaults.NOTHING;
myParagraphStyle.kinsokuSet = KinsokuSet.NOTHING;
