Hi,
For the available documentation, we understand that this is not intended.
As on how to do it, we understand that you should be able to change the *.elf file under the available debug configurations for the RTD examples (i.e. Siul2_Dio_ToggleLed_S32G274A_M7) and the debugger will load the *.elf you are pointing to:

But again, this is not intended.
Please, let us know.
