I have `ui componenet` form i want to disable one field dynamically when add only.

```
 <field formElement="select" name="classification" sortOrder="40">
        <settings>
            <dataType>text</dataType>
            <label translate="true">Classification</label>
            <disabled>true</disabled>
            <dataScope>classification</dataScope>
            <validation>
                <rule name="required-entry" xsi:type="boolean">true</rule>
            </validation>
        </settings>
        <formElements>
            <select>
                <settings>
                    <options class="Vendor\Module\Model\Object\Source\DivisionAgeFrontEndClass"/>
                </settings>
            </select>
        </formElements>
    </field>

```

`<disabled>true</disabled>` this line disable for all action.
i have refer [this](https://webkul.com/blog/disable-attribute-in-product-edit-admin-panel-in-magento-2/) link but not getting idea how to use this

Here is `Dataprovider.php` code

```
public function getData()
    {
        if (isset($this->loadedData)) {
            return $this->loadedData;
        }
        $items = $this->collection->getItems();
        foreach ($items as $model) {
            $this->loadedData[$model->getId()] = $model->getData();
        }
        $data = $this->dataPersistor->get('pacreg_team');

        if (!empty($data)) {
            $model = $this->collection->getNewEmptyItem();
            $model->setData($data);
            $this->loadedData[$model->getId()] = $model->getData();
            $this->dataPersistor->clear('pacreg_team');
        }

        return $this->loadedData;
    }

```
