Nano Server (Hyper-V) at SD Card?

Hello!

I have many 510-720 PE servers as MS Hyper-V 2012 R2 hypervisors and searching for update path to NanoServer.

all my servers has one or two SDcard (some of it are mirrored) and I'm interesting in installing and booting NanoServer from this SD not external USB2 stick.

any official way to implement it?

Thanks!
