No idea if this will work, but you could give it a shot…
#1 Boot into safe mode.
#2 Use nvidia inspector to edit the profile settings you want. **If this doesn’t work try #3**
#3 Use the geforce 3d profile manager to export the profiles to the desktop, and then open the file make the changes you want to the profile manually then import the file back afterwards. Then proceed to do #4 while still in safe mode.
#4 Search your ssd for nvdrsdb0.bin, nvdrsdb1.bin, nvdrssel.bin & nvdrswr.lk files and set them to read only. Doing this should prevent the profile settings from being changed when booted into normal windows mode.
Regarding setting the following files on read-only mode (nvdrsdb0.bin, nvdrsdb1.bin, nvdrssel.bin & nvdrswr.lk). It doesn't appear to be the solution, cause as soon as you insert any custom value on CP, and press Apply, the NVIDIA Recommended shows up straight away, as a selected option. So that doesn't give me enough time to set them to read-only. It's instantaneous. Give it a shot with dwm.exe. You'll see what I mean.
But thanks for the attempts to help me out with this.
I've got this "issue" posted on Nvidia discord tech support channel, with some additional pictures. Let's hope someone will pick this up, and eventually find a solution.
