Is your feature request related to a problem? Please describe.

Unable to have a periodic restart of the system even with HA if any cron task is required to sync to peer node

Describe the solution you like

A checkbox to ignore a task in the XMLRPC sync similar to other settings with this option.

Describe alternatives you considered

Disable syncing of all cron tasks between peers. Exceptions in expected configurations like this (syncing all but cron tasks between peers ) is how unexpected downtime happens.

Additional context

Would be a nice way to auto update the system alternating which node is updated.
