Keep Widows Update service and set Updates to Notify, then choose, which one you do not want.

Run those command as admin via CMD:

reg add "HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate\AU" /v "AUOptions" /t REG_DWORD /d 2 /f
reg add "HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate\AU" /v "NoAutoUpdate" /t REG_DWORD /d 0 /f

When some updates become available, use this tool to disable those, you do not want to install:

some updates cannot be hidden by the "Show or hide updates", e.g. the updates notification shows Windows Defender Definition is ready to be downloaded and installed, but the "Show or Hide updates" does not show this updates.

Windows Defender is AV protecting itself, the only way to stop its updates, is to disable it.

The Windows Defender has been disabled, but notification still shows its update.
