Correct, Tools customizer for z/OS is not included in ADCD package. We are working to include it for the next releases.
The jobs used to customize ADCD producs can be found on ADCD.LIB.JCL dataset. As we don't support specific products, if you don't find the needed samples in this data set. If it does not help, you should try support from DB2 product.
