Hi,
We have known the update is blocked in place because of various compatibility issues with numerous systems and hardware configurations.
Here is what you can do for Windows Update to show the feature update available notification:
1.Update your hardware drivers
2.Disable Core Isolation by going to Settings > Windows Security > Open Windows Security > Devie Security > Core isolation details.
3.Keep checking Windows 10 2004 release information page for mitigations and resolutions for Known issues.
Also, the update assistant can help you update to the latest version:

Currently in Microsoft Q&A we only support English, you may reply us in English and we can continue this thread discussing.
Thanks for your understanding.
Hope above information can help you.
