Hello Prashant,
Yes, you an achieve this within CSM. Do as follows:
Choose the device and select Firewall rules.
At the very top of the Access Rule table, you will find the "Filter" option.
After clicking "Filter", from the first drop down list choose "Conflict"; second box "has"; third box "Redundant Rules" or "Shadowed Rules". For this last option it can be one at a time.
Notice that if you want to delete all rules at once, CSM may hang for a very long time. I suggest you to do it by section of 100 rules (depending on how many rules your box has).
Let us know your results.
