Accessing graphics in Ubuntu which is installed as an app in Windows 10 HP

I have a windows 10 HP tower workstation with NVIDIA GeForce GTX 1070 graphics card, in which I installed UBUNTU 18.04 as an app (natively), by following the link:

https://www.howtogeek.com/fyi/windows-10-will-finally-offer-easy-access-to-linux-files/

I can access this graphic card in windows but I cannot access it in Ubuntu. I type the following command in the terminal:

lspci -k

And I got the following messages:

pcilib: Cannot open /proc/bus/pcilspci: Cannot find any working access method.

I also typed: lshw -numeric -C display but it did not return any value.
