Windows Version Update

Hi Folks,

We have few device left to upgrade from 1709,1809,1903,1909 to 21H2 or 22H2 version which is Microsoft supported updates, Best wat=y to upgrade via Intune
Even i have tried to update via below way

Even if you have downloaded some updates, there may be more available. After trying the preceding steps, run Windows Update again by selecting Start  > Settings  > Update & Security  > Windows Update  > Check for updates

Keep getting error device or showing as keep downloading only not happening anything ahead

Tried with Windows Updates assistant toll also no luck , not getting progress

Is there any way to get update manually or Through Intune

We have Intune only to deploying updates to devices

Appreciate your help

Thanks
