That would depend on how many drivers need to be installed/updated for your system. Including BIOS updates. And which version of Windows you are using. Microsoft made clear that it had only been released for Windows 10 Builds 1903 and 1909. This is because it has been released in a gradual (phased) roll out. Earlier windows builds will become eligible later. No one has said when.
This is one of the many reasons I keep my device up to date.
