I presume you have a number of meta-data names and associated values inside the metadata property as shown in an example below and you want to replace/delete/modify just one of them. Unfortunately, you can perform only replace-all-with. If you need to partially replace, you need to first get the array (as shown in the square bracket), manipulate it, and send it back.
"metadata": [ { "name": "satMeta", "persist": "true", "value": "Sat" }, { "name": "toyoMeta", "persist": "false", "value": "Toyo" } ],
This limitation is also discussed in ltm internal datagroup (can't modify a subset of records and need to replace-all).

"metadata": [

      "persist": "true",
      "value": "Sat"
    },
    {
      "name": "toyoMeta",
      "persist": "false",
      "value": "Toyo"
    }
  ],
