Removing a value from Repeater's sub field's array programatically

Hello,

I have a Repeater-type field named referral_code having a Text-type field named referral_value and the field group is attached to Options page.

I have managed to add a new field in WooCommerce user registration form to and validate against the values for the above Text field.

Now I am trying to remove one of the values if it has been used during WooCommerce registration.

In other words, need a way to programatically remove a value from Repeater’s sub field’s array.

If anyone can share sample code (even if it is showing how to remove one hard-coded text value) for this I would appreciate it.

Something along the lines of this non-working code:

add_filter( 'acf/load_value/name=referral_value', 'my_acf_load_method', 10, 3 );
/**
 * Remove a value from Repeater's sub field's array.
 *
 * @param mixed $value The field value.
 * @param int|string $post_id The post ID where the value is saved.
 * @param array $field The field array containing all settings.
 * @return $value Modified value.
 */
function my_acf_load_method( $value, $post_id, $field ) {
	unset( $value['acX54s'] );
	return $value;
}

This looks more like it:

// check if the repeater field has rows of data.
if ( have_rows( 'referral_code', 'option' ) ) {
	// loop through the rows of data.
	while ( have_rows( 'referral_code', 'option' ) ) : the_row();
		if ( 'acX54s' === get_sub_field( 'referral_value' ) ) {
			delete_sub_row( 'referral_value', get_row_index() );
		}
	endwhile;
} else {
	// no rows found.
}
