Hello,
first of all, I'd suggest to use something like phpMyAdmin to interact with your database. It's a battle proof tool with a lot of testing and securities, so if you have to pass raw data to the database, that should be your first choice.
That being said, you can create a WAF exception inside Admin Tools to allow those requests. Please take a look at this page of the docs, you will have to understand exactly which URL is called so you can create a rule to disable the WAF: https://www.akeeba.com/documentation/atwp/wafexceptions.html
