I have done it. So if you want to create Select values on the fly you can use this code. This code saves the “value : Label” though which is what I need. It sanitises the value you enter to slugify it, so its saved as “my-customer : My Customer” in ACFs field choices. If the value is to be the label its easily adapted.

You need to create a new text field for the “New” value you want to add. Then grab the old and new acf field_ids to use in the code.

function amity_pre_save_post( $post_id )
{
	// Assign the field IDs to variables
	$select_field_id = 'field_6346f63fec6c2';
	$select_new_field_id = 'field_634ac0abf3d60';
	
	// IF the new field value post cintains a value, then proceed
	if(isset($_POST['acf'][$select_new_field_id]) && $_POST['acf'][$select_new_field_id] != '')
	{
		// Assign the new value to label and value
		$label = $_POST['acf'][$select_new_field_id];
		$value = sanitize_title($label);
		
		// Get the ACF field settings
		$field = get_field_object($select_field_id);

		// Add the new fields value and label to the field settings
		$field['choices'][$value] = $label;
		
		// Update ACF field settings - adds new value into Select fields Choices in DB
		acf_update_field($field);
		
		// Asssign the Select field value to the new field value
		$_POST['acf'][$select_field_id] = $value;
		
		// Clear the new field value as we want it blank every time
		$_POST['acf'][$select_new_field_id] = '';
	}
}
add_filter('acf/save_post' , 'amity_pre_save_post', 1, 1 );
