WSUS has no option for syncing once per month. It requires a daily synchronization. Is it possible to change this to once per month through GPO or other means? Is the only other option to manually sync?
WSUS Synchronization Schedule – Once per month

You cannot achieve this directly from the native GUI of WSUS. It is not available as an option. Instead, you can extend the capabilities of WSUS with a third-party application like SolarWinds Patch Manager.
Preferably, if you've to, a better hack would be to set to manually perform the synchronisation in WSUS. And, then create a Windows task scheduler which would perform synchronisation with the help of available WSUS API.
