Hi Mian,

As per systemd.timer(7) you can change the timer to whatever frequency you would
like. The following should make update/upgrade happen monthly.

    OnCalendar=*-*-05 00:00

Probably you should disable apt-daily.timer all together and create a new one
named apt-monthly.timer so that your changes are not overridden by future
upgrades.  Also, you have to create a apt-monthly.service accordingly.

Modifications to `/etc/apt/apt.conf.d/10periodic` should still be needed if
you would like to go fully unattended.

    APT::Periodic::Unattended-Upgrade "1";

Still `/etc/apt/apt.conf.d/50unattended-upgrades` controls the packages you
would like to upgrade.

Regards,

Roy
