How to Block acunetix ?

Hello there,
Although the Comodo waff is active, unfortunately the Acunetix program is performing smoothly and without problems.
It is not blocked in any way.
We use the Plesk Juggernaut firewall.
Normally it should be reflected in the audit log.
But we have not found any way to prevent it.
Any solution suggestions?

Hello BerkeT. CWAF rules has detection for Acunetix (defined in file bl_scanners_headers). Please provide version of modsecurity, webserver, CWAF rules. Also if possible please provide logs for Acunetix scan.
