eGpu pass through

I have been tinkering with the lattepanda Alpha for a few weeks and am quite pleased so far. I was excited to find out one can connect an external gpu to the m.2 slot, my only concern is that the gpu I would like to use was scavenged from an old gaming laptop (gtx880m) while the gpu is quite capable it does not have an external video output of any kind . Is there a way to pass the video output from the gtx through to the hdmi output on the lattepanda alpha?
