If you do not want to change the proc you cannot over-ride the program name in a proc unless it is a symbolic. That is a good reason to make all programs in procs symbolic. If it is a symbolic you could over-ride it to something that does not exist. Another way is to over-ride adding or changing a DD to a DSN that does not exist with a disp like shr.
Either of these ways would get a JCL error and not execute the following steps.
If you are changing the proc delete or comment out the steps you do not want to execute.
