Acer Aspire with Nvidia Optimus "technologi" problems


I’m looking for an nvidia-driver-optimus freebsd driver for my Acer Aspire E17 hybrid graphics notebook.I would like to setup my machine by these:

My cards:

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07)

lspci | grep 3D
01:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 940M] (rev a2)

Maybe if somebody know other method, please write it down. Thank’s!
