Issue with SVP 4

Hello, I am using SVP 4 with a laptop (XPS 15 9560) with an eGPU (at times). SVP will run fine when my laptop is used in "laptop mode" and I have no issues. The issue I am having is that it's not working when I use my laptop closed with my eGPU. I suspect this is because of the program running on intel graphics, and that because the intel card is disabled when I use my egpu, the program doesn't work. I have tried to switch the graphics card to my nvidia one when doing this slope game, but it isn't working. Is there anything I can do?
