On windows its possible to turn it off with geforce-experience and it seems that it doesn't do it definitly, it does it by software on the driver...

        nvidia-settings --assign GPULogoBrightness=0
All attributes can be found by nvidia-settings -q all
Refer to this post for starting it at boot
The solution I choosed is to put in my ~/.xinitrc according to this post you can do it by the following command echo "nvidia-settings --assign GPULogoBrightness=0" >> ~/.xinitrc if you want it systemwide put it into your /etc/X11/xinit/xinitrc
