If you want to update 20 columns i would recommend below approach

No! a!update() only modifies the fields you specify and automatically preserves all other columns unchanged.

I tried to replicate your issue with map.
Try it once for your CDT and let me know if that works for you.

a!localVariables(
  local!request_data: a!map(
    requestId: 123,
    requestType: "Service Request",
    casettnotes: {
      a!map(
        id: null, 
        issuetype: "pending", 
        casenote: "First case note - pending review",
        createdDate: today()-3
      ),
      a!map(
        id: null, 
        issuetype: "approved", 
        casenote: "Second case note - approved by manager",
        createdDate: today()-2
      ),
      a!map(
        id: null, 
        issuetype: "review", 
        casenote: "Third case note - under review",
        createdDate: today()-1
      ),
      a!map(
        id: null, 
        issuetype: "failed", 
        casenote: "Fourth case note - THIS NEEDS UPDATE",
        createdDate: today()
      )
    }
  ),

  local!newNoteValue: "UPDATED: Fourth row has been successfully modified",

  local!updatedData: a!update(
      local!request_data,
      "casettnotes",
      a!forEach(
        items: local!request_data.casettnotes,
        expression: if(
          /* Condition: Update 4th row OR where issuetype = "failed" */
          or(
            fv!index = 4,
            fv!item.issuetype = "failed"
          ),
          a!update(
            fv!item,
            "casenote",
            local!newNoteValue
          ),
          fv!item
        )
      )
    ),
  
  local!updatedData

RE: need to update nested cdt column data

It is very difficult to understand the structure this way. Can you try creating a map with how actually your cdt structure is and for which cdt which field you are facing challenge. Some example of what your input is and expected output is will be helpful too.
