A 64-bit signed driver has been compiled by bbs.wuyou.net forum member Yamingw.

The signed driver is available here (and for convenience is also available here). I am not able to verify whether this file has been modified.
The SVBus driver can be installed to an offline system using the DISM tool. E.g. -
