Varjo VR-1 on DCS and eye tracking activation?

Hey guys!
I'm the lucky owner of a Varjo VR1 and coming back to DCS right now, and to make the 80PPD work with my 3080, I'm trying to gain every FPS possible. knowing that the Varjo VR-1 has an eye tracking system in it, how can I utilize it for dynamic FOV rendering? I didn't find much online, but maybe someone has some insights here. 🙂
