Readonly radio field

I have a acf_form(); in the front end which outputs a repeater. I want to make some rows readonly. Each row contains a radio button field.

The code below works great with text fields, but not with radio buttons. Any ideas?

function my_load_field($field) {
  $field['readonly'] = 1;
  return $field;
}
add_filter("acf/load_field/name=radio_button", "my_load_field");

Radio fields do not support readonly. It’s not ACF, it is the way that radio fields work. https://stackoverflow.com/questions/1953017/why-cant-radio-buttons-be-readonly

Thanks for your answer. Does the same go for disabled? This code seems to work for me. Is it possible to achieve that with a filter for ACF radio fields?

<input disabled type="radio" name="" value="">

I’m pretty sure you can set a field to disabled https://www.advancedcustomfields.com/resources/acf-prepare_field/

$field['disabled'] = true;

but I am not entirely sure at the moment.

I tried that as well. But it only applies to my text fields.

function my_acf_prepare_field( $field ) {
   $field['disabled'] = true;
   return $field;
}
add_filter('acf/prepare_field', 'my_acf_prepare_field');

I just looked at the ACF code and it appears it allows more granular control for ratio fields, at least that’s the way it appears.

function my_acf_prepare_field( $field ) {
   $field['disabled'] = array(
      // set each value option you want to disable
      'value1',
      'value2',
      // etc
   );
   return $field;
}
add_filter('acf/prepare_field', 'my_acf_prepare_field');
