How update value recyclerview element in real time?

How can I make an item value update in real time? I have a list. Elements are added to it. (list of connected devices via bluetooth). Every cell contains information: name, date. How can I change, for example, the name in any cell without updating the all list? Now when I call update method information changes in the first list element (in position 0) but I need that I could change value any position and any element when I call update method. I read about DiffUtil class. But I'm not sure that is suitable option for me. So, I have model class:

data class Device (
    var name: String,
    var date: String
)

adapter:

class CustomRecyclerAdapter(private val values: MutableList<Device>) :
        RecyclerView.Adapter<CustomRecyclerAdapter.MyViewHolder>() {
    
        override fun getItemCount(): Int {
            return values.size
        }
    
        override fun onCreateViewHolder(viewGroup: ViewGroup, viewType: Int): MyViewHolder {
            val view = LayoutInflater.from(viewGroup.context)
                .inflate(R.layout.list_item, viewGroup, false)
    
            return MyViewHolder(view)
    
        }
    
        override fun onBindViewHolder(viewHolder: MyViewHolder, position: Int) {
            var device: Device = values[position]
            viewHolder.bin(device)
        }
    
        class MyViewHolder(view: View) : RecyclerView.ViewHolder(view) {
            var textName: TextView? = null
            var textDate: TextView? = null
         
            init {
                textName = view.findViewById(R.id.name)
                textDate = view.findViewById(R.id.date)
            }
    
            fun bin(device:Device) {
                textName?.text = device.name
                textDate?.text = device.date
            }
        }


class MyFragment : Fragment() {

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        val view = inflater.inflate(R.layout.fragment_upload_card, container, false)
        var recyclerView = view.findViewById(R.id.recyclerView) as RecyclerView
        recyclerView.layoutManager = LinearLayoutManager(activity)
        adapter = CustomRecyclerAdapter(list)
        recyclerView.adapter = adapter
        return view
    }

    private fun addItem() {
        var device = Device("DeviceName", "date")
        list.add(0, device)
        adapter?.notifyItemInserted(0)
    }

    fun update() {

        list[0].run {
            name = "newName"
            date = "newDate"

        }
        adapter?.notifyDataSetChanged()
    }

Maybe I have to use RX here? But I don't understand how in this case
