which issues are you having?
Please remember that Aurora is just a MySQL-compatible database hosted on AWS infrastructure. Basically they will end up to manage it to keep performances acceptable, without you to worry about tweaking any database configuration.
As long as the writing and reading connections are the same, there is nothing do to. If they are different (ie you have an endpoint to write data and another one to read them) you can't use WordPress (or Joomla) out of the box; you'll need some third party plugin. If that's the case, Admin Tools won't be affected, however Akeeba Backup will be.
Finally, Admin Tools can do very little for you: we have utility tools to tweak your .htaccess file, but that will affect Apache, the webserver that is serving the requests, not the underlying database.
