Seems not clear but flags *could be combined*, as per other flags.
For example:
<?php
# wannabe noticed about all errors except those about indexes
$driver = new mysqli_driver();
$driver->report_mode = MYSQLI_REPORT_ALL & ~MYSQLI_REPORT_INDEX;
?>
(PHP 5, PHP 7, PHP 8)
mysqli_driver::$report_mode -- mysqli_report — Sets mysqli error reporting mode

Depending on the flags, it sets mysqli error reporting mode to exception, warning or none.
When set to MYSQLI_REPORT_ALL or MYSQLI_REPORT_INDEX
it will also inform about queries that don't use an index (or use a bad index).
As of PHP 8.1.0, the default setting is MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT.
Previously, it was MYSQLI_REPORT_OFF.
