Enabling Advance Optimus by modifying BIOS of Legion 7i-2020

[Rana@92]

Hello All,
I recently bought a lenovo legion 7i 2020 model from amazon india and bios was updated to v4.08(Linked Below) however advance optimus is disabled on this laptop so i want to  modify the stock bios so that it gets enabled,advance bios settings are available by pressing fn+R+N and then saving the bios options and if i go to system agent configuration->graphics configuration->changing primary display i can get advance optimus to show in nvidia control panel but laptop internal display remains black but i can see options when connected via HDMI
So please enable advance optimus and thanks in advance. sorry i forgot to mention also unlock stat port ssd in the bios because by deafult only nvme is supported.
