Set custom field to non-editable

Hello, I’m looking for some help ??

I have a two custom fields for phone and company. All works well and is visible on the account page. I like to change the company field into a non-editable field.

The field is set to – not editable by user – in the registration form, though it seems that the custom code overwrites this setting and makes the custom field editable again for the user. I need company (bedrijf) to be not editable for the user, the same as the username is locked.

I’ve added this to my functions.php to add the extra meta fields:

// SHOW CUSTOM FIELDS ON ACCOUNT PAGE
add_action('um_after_account_general', 'showUMExtraFields', 100);

	function showUMExtraFields() {
	  $id = um_user('ID');
	  $output = '';
	  $names = array('phone_number', 'company_name');

	  $fields = array(); 
	  foreach( $names as $name )
		$fields[ $name ] = UM()->builtin()->get_specific_field( $name );
	  $fields = apply_filters('um_account_secure_fields', $fields, $id);
	  foreach( $fields as $key => $data )
		$output .= UM()->fields()->edit_field( $key, $data );

	  echo $output;
	}

add_action('um_account_pre_update_profile', 'getUMFormData', 100);
	function getUMFormData(){
	  $id = um_user('ID');
	  $names = array('phone_number', 'company_name');

	  foreach( $names as $name )
		update_user_meta( $id, $name, $_POST[$name] );
	}
