This time I'm using the Stretch Alpha 6 DI. I successfully loaded the 
efivars module as you suggested, however the efivarfs interface remains 
inaccessible, it still cannot be mounted.

I suppose that the efivarfs module has to be loaded too but there is no 
trace of efivarfs.ko in the DI and I didn't find any udeb containing 
it. Should I load it someway from an external source?

Thanks for your help!
