How to change persist value (in F5 LB) to "None" using rest api

Using rest api I am able to change default persistence profile from None to dest_addr / source_addr. But I am not able to change it back to "None" (using rest API) from dest_addr / source_addr.   ...

Use 

null
(without quotation) or 
{}
(means empty object). Also, use 
PATCH
for modification. For example (using curl),

Check the current persistence configuration of the virtual 

VS-HTTP
(with 
dest_addr
).

 curl -sku user:pass https:///mgmt/tm/ltm/virtual/VS-HTTP?\$select=persist

Output as below:

{ persist:
   [ { name: 'dest_addr',
       partition: 'Common',
       tmDefault: 'yes',
       nameReference: { link: 'https://localhost/mgmt/tm/ltm/persistence/dest-addr/~Common~dest_addr?ver=12.1.2' } } ] }

Change it to "none".

 curl -sku user:pass https:///mgmt/tm/ltm/virtual/VS-HTTP \
  -H "Content-Type: application/json" \
  -X PATCH -d '{"persist":{}}'

Now check it again using the GET request. The output should show:

{}
