Can Kaspersky free antivirus be turned off except for system watcher to work side-to-side with active Microsoft defender without causing software conflict or system instability?

No, running two antivirus programs simultaneously can cause conflicts and system instability. Kaspersky's System Watcher is part of Kaspersky's antivirus package, so it can't be used independently while Microsoft Defender is active.
 
If you already have Kaspersky installed, I recommend using Kaspersky as main AV and activate MD periodic scanning:

I do not like its network protection module replacing websites certificates; vulnerability and slower browsing with CPU spikes while scrolling.
You can disable its certificate replacing feature. Browsing will be fast and known malicious host will still be blocked.

The problem is that it will show you red flag in the status bar if you turn off its basic protection modules, try to configure its settings to fit your needs as much as possible.

No, thankfully Kaspersky doesn't show red flag for disabling this feature. Avast doesn't either.
