Set selectable during runtime

Hello folks,

so i started to use that little "toggle selectable" icon in the editor, which is very neat, since it toggles the flag for all nested objects as well for stuff i usually do not want to select.

I need a solution to set that flag during runtime via code. The usecase is like this:

As shown in the picture i have two parent objects which get populated during runtime with debug-objects i don´t want them to be selectable. I can set the flag for the parent pre-runtime, but that still means the instatiated children are all selectable


Is it possible to set that property during runtime via code?
