Please bear in mind this type of graphics customization is not supported by our technical support department. I would recommend waiting for another community member that could have experienced same issue and post any help for your inquiry.
Okey, I will answer it myself. After a few hours of testing I found out that you have to delete the igfxpers.exe from the autostart (HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Persistence).
After that persisting HKLM\SYSTEM\CurrentControlSet\Hardware Profiles\Current\System\CurrentControlSet\SERVICES\iAlm with regfilter did the trick.
