We have update one of our table which has around 150 million rows for each partition and such 12 partition exists . We want to use dbms_parallel_execute
functionality to achieve this but I am not able to figure out how to pass partition specification for creating the chunks.
Please let me know if you have some pointers.

Great idea of spiting data to equal size chunks. May be scary at first look but really works. You can adopt them to your update with dbms_parallel_execute.
