iControl REST (11.6): REST API for clearing DNS cache

I am trying to clear DNS cache using iControl REST apis, but i couldn't find any. I can get information about DNS cache using following REST api.

GET

https://localhost/mgmt/tm/ltm/dns/cache/resolver

GET

https://localhost/mgmt/tm/ltm/dns/cache/transparent

GET

https://localhost/mgmt/tm/ltm/dns/cache/validating-resolver

Using above apis, I can get information about the added DNS caches, but there is no way to clear these. On UI, we need to go to the statistics page to clear the cache, but again there is no way to check statistics using REST.

I have also figured out tmsh common for clearing DNS cache, which is delete

ltm dns cache records rrset cache 

. Now I am trying to convert this command into REST api which is unfortunately not working. I tried following:

DELETE

https://localhost/mgmt/tm/ltm/dns/cache/records/rrset?options=cache+DNS_Cache_name

Could somebody help me out to clear DNS Cache using iControl REST?
