Microsoft Surface Pro 4

I am trying to install Big Sur on Microsoft Surface pro 4.
I made it work up to the install screen but can't make it work keyboard and track pad.
It work in clover but when it boot up the Big Sur Recovery keyboard/track-pad does not work.
I have 1 USB so another keyboard and mouse out of option and my docking station also don't work on it.
i got the product id and vendor info but can't find the info how to add in it?
