I had spent days for solution, but nothing work so far, please help!
Things I had tried:

Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "TearFree" "true"

Section "Device"
Identifier "Intel Graphics"
Driver "modesetting"
Option "AccelMethod" "glamor"
Option "DRI" "3"

(both of these caused Xorg failed to boot...)

lspci -k

Intel HD 520 is notorious for tearing and other issues (even on Windows). Any way to disable the 520 from your BIOS/EFI and then just troubleshoot the GTX solo? Sorry if I'm missing something obvious, just trying to isolate.

It appears you are loading the both the proprietary and opensource drivers for the nVidia. I don't use nVidia, but I think you should blacklist the nouveau drivers or remove the proprietary ones (someone more familiar with nVidia setups will/should chime in)

Thanks, too bad mine is a nvidia optimus device (Acer Aspire V15 Nitro), which doesn't have such feature in BIOS/EFI to disable either one of the graphic card.

If you opt for the proprietary drivers, here is some good info on Optimus on Fedora:
