Zombie requests overloading CPUP usage to 100%

Hi there,
I noticed that suddenly the CPU of my server is full. I tried htop and sort the jobs/requests.
I came to know that following request is overloading the CPU very badly.

/usr/bin/php8.1 -q /PATH_TO_MATOMO/console climulti:request -q --matomo-domain=<domain-name> --superuser module=API&method=CoreAdminHome.archiveReports&idSite=INTEGER_VALUE&period=year&date=2022-01 01&format=json&segment=visitorType%3D%3Dnew&trigger=archivephp&pid=A_VERY_LARGE_STRING_FOR_PID&runid=19943

When I tried kill these requests using sudo kill -9 and I found that as many as I kill they get started new one. Then I also tried to search if they are being started on my system with some cronjob but I could not find any origin of these requests.
I searched about these request on google and found following topic.

Questions: How I can avoid these requests? Do these requests are necessary part of archiving in the latest version of Matomo? Can I stop it at network level for example by apache web server?
