I loaded their 20H2 preset, and undid the Defender changes. It appears to work for me.

You're on v2.1.1.7917 (May 2021), don't know if that makes a difference -- not for Defender, but the Atlas OS preset was saved on 2.3.6.8792.
NTLite can comfortably import older presets and update the XML, but not sure if it's guaranteed in the other direction?
Here's my undo's from the Atlas OS preset:
Code:
<c>Microsoft.Windows.SecHealthUI 'Windows Defender'</c>
<c>securitycenter 'Security Center'</c>
<c>systemguard 'System Guard'</c>
<Tweak name="DefenderApiLogger\Start">0</Tweak>
<Tweak name="DefenderAuditLogger\Start">0</Tweak>
<Tweak name="Notifications\DisableNotifications">1</Tweak>
<Tweak name="Notifications\DisableEnhancedNotifications">1</Tweak>
<Tweak name="Windows Defender\DisableAntiSpyware">1</Tweak>
Also not sure why Atlas OS is stuck on the Nov 2020 Out of Band build (19042.631). I don't see any reason why it can't be applied to a more current release unless the author doesn't want to requalify it.
I'd upgrade NTLite if possible. If your license is expired, you won't get newer features but at least the bug fixes will work on the previously supported features. Maybe someone else can repeat my testing.
