Hi, thank you for reaching out to the Microsoft Q&A forum. I’m happy to help.
The Extended Security Updates (ESU) program is being gradually rolled out to all eligible Windows 10 devices worldwide. If your device meets all the requirements, it should become available within the coming days as part of the gradual rollout. I recommend continuing to apply updates, and it should automatically appear on the Windows Update page in Settings.
To enroll in the Consumer ESU program, please check the prerequisites in the link below (scroll down to the bottom).
