You can if you want to use get_post_meta() instead of ACF functions. However, this will return unformatted values and you’ll need to format them yourself if needed. The meta keys for repeaters look like "{$repeater_name}_{$row_index}_{$sub_field_name}" and you would use something like get_post_meta($post_id, $field_name, true) https://developer.wordpress.org/reference/functions/get_post_meta/
