You need to do this on the load value hook for the repeater

example:

add_filter('acf/load_value/name=your-repeater-field-here', 'preload_repeater', 20, 3);
function preload_repeater($value, $post_id, $field) {
  if (!empty($value)) {
    // this repeater already has a value do not change it
    return $value
  }
  // code here to populate repeater

  // this is an example of what ACF is expecting for the value
  // the repeater value is an array
  $value= array(
    // each row is a nested array
    array(
      // each nested row array is made up of "field key" => "value pairs"
      'field_012345' => 'value for this sub field',
      'field_123456' => 'value for 2nd sub field',
      // etc....
    ),
    // second row
    array(
      // etc...
    ),
    // etc...
  );

  return $value;

}
