Dell ControlVault Driver and Firmware for latitude e7440

Hi

I have two devices  that are listed in Other Devices

1. Broadcom USH
2. Broadcom USH w/swipe sensor

I don't see the drivers for Windows 10 64 bits under security (they are there for windows 8.1); do you think that they will be available soon; and what about the ControlVault Firmware.  Or can I use ones listed for windows 8.1?

I have a latitude E7440 (mid 2013)

thanks
