如何在Material-UI V5 (@mui/lab)日期选择器组件上设置空标签？

import { DatePicker, MobileDatePicker, LocalizationProvider } from '@mui/lab';
import AdapterDateFns from '@mui/lab/AdapterDateFns';
import { Box, Button, Typography } from '@mui/material';

function MyDatePicker() {
  return (
    <LocalizationProvider dateAdapter={AdapterDateFns}>
      <DatePicker
        label="选择日期"
        value={null} // 设置初始值为null
        renderInput={(params) => (
          <Box sx={{ display: 'flex', alignItems: 'center' }}>
            <input {...params.inputProps} />
            <Button variant="outlined" onClick={params.openPicker}>
              选择
            </Button>
          </Box>
        )}
      />
    </LocalizationProvider>
  );
}

function MyDatePicker() {
  return (
    <LocalizationProvider dateAdapter={AdapterDateFns}>
      <DatePicker
        label="选择日期"
        value={null} // 设置初始值为null
        renderInput={(params) => (
          <Box sx={{ display: 'flex', alignItems: 'center' }}>
            <input {...params.inputProps} value="" /> {/* 设置空的value属性 */}
            <Button variant="outlined" onClick={params.openPicker}>
              选择
            </Button>
          </Box>
        )}
      />
    </LocalizationProvider>
  );
}
