Hi Santhosh_rkk
Thanks for posting the thread on our forum

According to your description, it seems that you want to know if there is a direct Windows commands to disable the office updates .
- As you mentioned, the first way is open an office application>File>Account>update office>to disable office update.
- The second way is opening Settings> Update & security > Windows Update> Advanced options > Turn off the option labeled Receive updates for other Microsoft products when you update Windows.
- Besides, you also can Open the Windows 10 Store app> Click on the three dots icon and then click Settings> App updates> turn off the Update apps automatically option.
