Welcome to Microsoft Q&A Platform.
If you are one of the people who is unable to grab the May 2020 Update via Windows Update, you could force the download using Windows 10 Update Assistant -- but be warned that this could mean that you end up encountering problems. Perhaps the best course of action is to follow Microsoft's advice, and just sit back and wait for when your system (hopefully) is compatible with the update; presumably when driver and hardware issues have been resolved.
How to use Update Assistant:
Click the Update now button under the Windows 10 May 2020 Update heading.

This will download the Windows 10 Update Assistant which will guide you through the process of grabbing the update.
In fact, Microsoft warns:
We recommend that you do not attempt to manually update using the Update now button or the Media Creation Tool until this issue has been resolved.
