Following worked for me to get the dgpu switched off on an xps 15 9560.
1. Purge nvidia
2. Install nvidia and do not reboot
3. Install bumblebee-nvidia
4. Set bootparameters are to acpi_rev_override=1 and i915.modeset=1
If you have tlp installed uncomment:
#RUNTIME_PM_DRIVER_BLACKLIST="amdgpu nouveau nvidia radeon"
Could not get optirun to work. Switching to nvidia with prime works, but switching back to intel gives a black screen with only the cursor visible. Making goto step 1. necessary.
