Thank you very much Renate!
I replied to your PM with details.

Meanwhile, for anyone interested reading this post in future, after installing Nova launcher (this is important! Have a sane launcher before you disable anything OEM, just is case ) I successfully disabled those:
Code:
# Neo browser
pm disable org.chromium.chrome
# Some substitute apps (they are fine, but meh)
pm disable com.simplemobiletools.clock
pm disable com.simplemobiletools.musicplayer
pm disable com.simplemobiletools.voicerecorder
pm disable com.onyx.kreader
pm disable com.onyx.android.note
pm disable com.onyx.mail
pm disable com.onyx.calculator
pm disable com.onyx.pinyinime
pm disable com.onyx.appmarket
pm disable com.onyx.dict
pm disable com.onyx.android.production.test
pm disable org.codeaurora.bluetooth.batestapp
pm disable com.android.email
pm disable com.android.quicksearchbox
# Google play & Co.
pm disable com.android.vending
pm disable com.google.android.gms
pm disable com.google.android.gsf
pm disable com.android.printspooler
# the Onyx launcher and useless OTA (Kon-Tiki 1/2 are updated only locally from PC)
pm disable com.onyx.android.onyxotaservice
Interesting notes:
1) Upon a fresh boot with Nova launcher as a main launcher, app optimizations do NOT work unless you manually enter sleep. Maybe this is because the lock screen is still under control of the framework.apk, which was usually tied to start with Onyx launcher.
You can see this by yourself. Set a device password like I did, reboot and when prompted to enter the pass code, just press the power button. You will see the screensaver picture to be tiny and weirdly oriented.
Sorry, that was wrong. Disabling Onyx launcher (com.onyx) actually breaks lock screen and app optimizations, as well as block you from reaching the update button.
Once you enter the pass code and lock again - everything is back to normal. I guess this is because the pass code is native Android, while the lock screen is the Onyx framework, which is inactive at this stage.
Anyway, after boot and entered pass code just lock and unlock the device, and app optimization will work as usual.
2) Onyx launcher's disabled state does not break too much stuff: rotation, app optimizations, swipe gestures on the bottom, screenshots, Navigation ball, Glow light control, Task manager, screen modes, extra scroll buttons. Only multi-window mode is somewhat broken showing less apps that support it, but I don't use it anyway. With such a small screen a fixed portions of the divided screen there is no much use for it.
3) I will probably occasionally re-enable/disable the Onyx launcher to set different screensavers and swipe gestures. But that all I'd need from it
