How to switch to a different subscription plan - Apple Support
- Switch your Apple subscription to a different type, such as a monthly plan, annual plan, or student plan.
With a side note that you cannot change all subscriptions. For example, an iCloud subscription is charged monthly, and it is not possible to change is to annual.
In principle, you would have to check for each app whether it is possible.
