ExtendScript - Change starting engine

Hello friends,

i am currenly working on customizing FrameMaker with ExtendScript.

When I completely restart ExtendScript Toolkit, I always have to change the "main engine" (don't know if this is the correct term) of my script

from "ExtendScript Toolkit CC" to "Adobe FrameMaker 2017" via this panel:

Is there a way to modify the code, which implements this functionality automatically without user input as shown in the picture above?

Thanks a lot!

Selim
