I think you are mistaken, in my bios I've set it to share no system memory, yet when I open up Call Of Duty: WWII it shows as having 1GB of GPU Ram. I went back into BIOS and set it to share 1GB, now the game shows 1877/945 MB being used, I went back and set it to share 3.5GB, but now it still says 1877/945 MB, I opened up task manager and see that under GPU, the full dedicated 1GB is in use but under the 3.5GB Shared memory it is 0.0/3.5 GB. So I guess I solved my issue but a new was arises, how do I use the new 3.5gb shared memory?
