Prompt [Q] How to change default.prop (not build.prop!!!)

I want to change some proprieties of the default.prop(yeah, not build.prop )
But I don't know to change that in Rom 4.2 onwards (I could change it in Kayant's 4.1.1 AOKP Rom by changing /system/bootmenu/config/default.prop but this method don't work on another CM android 4.2 Rom, because of 2ndboot?)
How to change the default.prop (or the corresponding values)?
(Coz the app I want to use is checking those values, and refuses to start if it detects or ro.debuggable=1 or persist.service.adb.enable=1)
(I want to move to a new Rom but I have to solve this problem first)
