I have an xps 9570 running 18.04 Jackhack96 version. I have recently realized that my battery life was getting worse. Opening powertop I saw the following

Summary: 2274,6 wakeups/second,  0,0 GPU ops/seconds, 0,0 VFS ops/sec and 55,4% CPU use

The interesting part is that seemingly the fingerprint sensor (which doesn't have compatible drivers with Ubuntu afaik) is drawing a fair amount of power. Is there a way to disable it completely? Running lsusb I get the following:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 27c6:5395

Thank you!
