Here are some steps that we can follow to take the control back instead of managed by the organization:
1.Press "Win+R", put in "gpedit.msc" and press Enter to open GPO editor.
2.Navigate to Computer Configuration > Administrative Templates > Windows Components > Windows Update.
3.Set "Configure Automatic Updates" to Not Configured and restart the PC to apply the setting change.
