Keep in mind that a skipped change is a record that gets created when you have made a change (i.e., a configuration or customization) to your Now Platform instance and ServiceNow updates the same records as part of a new release (e.g., from Orlando to Paris).
ServiceNow upgrades will not overwrite changes you have made, so you will need to review your skipped changes and determine whether to revert to base, merge, or keep your changes
Revert to base meaning accepting OOB version and Retaining meaning keeping your customization
To answer your question yes you can deactivate ACL afterwards. You can select revert to base version to accept upgraded ACL
Another Option you can explore is merge - Merge the change to incorporate new
release updates into your instance while keeping your customization (i.e., enhance the customization). You can use the Resolve Conflicts form to compare the base system version with the customized version of a record and reconcile the differences before merging.
