First step is to create the following file, it should disable cpanellogd:

touch /etc/cpanellogddisable

Now kill all cpanel logd process by finding the PIDs

ps aux | grep cpanellogd
kill -9 PID#

Above please replace PID# with the PID number for the process running for cpanellogd.

Additionally, to ensure cPanel restart does not start cpanellogd (I tested and even with the /etc/cpanellogddisable file, cPanel restart still tries to restart the process), you would want to move the following files:

mv /usr/local/cpanel/cpanellogd /usr/local/cpanel/cpanellogd.bak
mv /usr/local/cpanel/libexec/cpanellogd /usr/local/cpanel/libexec/cpanellogd.bak

After doing the above steps, cpanellogd should no longer run on your machine.
