When you create an Intune "Windows 10 or later updates" Configuration Policy for a deployment ring, you can set your Deadline for Feature Updates. This gives your users space between getting the content for the update and when a restart will be required (in days) to apply it. If you are looking to stagger across your environment, you should be using a ring-based approach, to cascade out at different start times to different device populations. Check out Configure Update rings for Windows 10 and later policy in Intune | Microsoft Learn for details on how to set up deployment rings that have different start times to help stagger your deployments to get an eventual rollout completed in your environment.

Nesav132 ,  great question!   We are actually in the final steps of completing adding an option to make the update optional to end users, and hoping you'll see that in Feature update policies in Intune in the next month or two.   It won't pre-download the update, but will enable the end user to choose if they want to install it.  Later, when you are ready to make it required for everyone, you can just change the setting in your policy, and it will become required for everyone who hasn't installed it yet.
