title: How to override styles for material-ui TextField component without using the MUIThemeProvider?
body: <p>How would I hide / remove the underline in a TextField component <strong>without</strong> using the following code:</p>
  
  <pre><code>const theme = createMuiTheme({
    overrides: {
      MuiInput: {
        underline: {
          '&amp;:hover:not($disabled):before': {
            backgroundColor: 'rgba(0, 188, 212, 0.7)',
          },
        },
      },
    },
  });
  </code></pre>
  
  <p>I would like to do it with props and according to the docs: <a href="https://material-ui.com/api/input/" rel="noreferrer">https://material-ui.com/api/input/</a></p>
  
  <p>I should be able to change the underline prop, but it does not work.</p>
