You can use the CSS property pointer-events
to disable the click event on any element:
https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events
// To disable:
document.getElementById('id').style.pointerEvents = 'none';
// To re-enable:
document.getElementById('id').style.pointerEvents = 'auto';
// Use '' if you want to allow CSS rules to set the value
