Assuming you still want Windows to download and install updates automatically and you just want it to never reboot by itself:
>in the Group Policy Editor, go into Computer Configuration>Administrative Templates>Windows Components>Windows Update
>change both of the policies in pic related to be like in pic related

The policy on the left has to be changed to pic related because as it says in the no auto-restart policy:
>This policy applies only when Automatic Updates is configured to perform scheduled installations of updates. If the "Configure Automatic Updates" policy is disabled, this policy has no effect.

TL;DR if both policies are configured exactly like pic related, you'll download and install all updates automatically but NEVER auto-restart
It's my configuration and my machine has never restarted by itself ever since I've set it like that
