To try and prevent these unintended consequences and enable you to stay with a given release of Windows 10 for the longest duration, beginning with Windows 10, version 2004, we no longer display deferral options on the Windows Update Settings page under Advanced options. This ensures that you have control over, and visibility into, exactly when to install the latest Windows 10 feature update until you near end of service. The ability to set deferrals has not been taken away, it is just no longer being displayed on the Settings page.
This looks like a poor design decision. For one thing, removing controls does not "ensure that [I] have control". For another, these explanations still do not justify the removal of the deferral controls for the monthly updates.
If it was me, I'd leave the controls to be, and added a "Maximum" item to the drop-down list that controlled the feature update deferral. This "Maximum" item would enact the behavior that this article explains. But then again, if it was me, I'd have resolved the problem in the source by ensuring that updates have such quality that nobody needs deferring them in the first place.
