Try to disable hours for the <TimePicker/> component by the showTime.disabledHours prop. But it does not disable the hours. The hours can still be selected.

import React from 'react';
import 'antd/dist/antd.css';
import './index.css';
import { DatePicker } from 'antd';
import type { DatePickerProps } from 'antd/es/date-picker';

const onChange = (
  value: DatePickerProps['value'],
  dateString: [string, string] | string
) => {
  console.log('Selected Time: ', value);
  console.log('Formatted Selected Time: ', dateString);
};

const App = () => (
  <DatePicker
    showTime={{
      showHour: true,
      showMinute: false,
      showSecond: false,
      disabledTime: () => ({
        disabledHours: () => [
          0, 1, 2, 3, 4, 5, 6, 7, 8, 18, 19, 20, 21, 22, 23,
        ],
      }),
    }}
    onChange={onChange}
  />
);

export default App;
