Hi,
Assuming that you have set WP’s DISABLE_WP_CRON constant to true in your wp-config.php
file as the constant is used for disabling internal WP-Cron, then to ensure that all WP’s scheduled events (e.g automatic-updates event) can be run properly even the if internal WP-Cron is disabled, you will need to set up an external cronjob, which is usually can be done from within your hosting panel and add a new crontab job that will access the wp-cron.php
file to look for past due or due now scheduled events and run the them in a specific time interval. You might also want to install a cron management plugin like WP Crontrol that allows you to add, modify, and manage WordPress scheduled events directly from the WP dashboard. You can also define custom time intervals for the automatic updates schedule.
Thanks
