SDRSharp/Airspy on Debian

Hi guys I am attempting to install Airspy (before known as SDRSharp) on my Debian 9.0 and I am following this link: https://rtlsdr.org/softwarelinux When it gets to the line of Airspay Installation it quotes "Don't forget to blacklist the kernel driver as mentioned here <https://github.com/airspy/host/wiki/Troubleshooting%5Dhere%5D.%20%20*%20Download%20the%20latest%20zipfile%20copy%20of%20SDR#%20from%20[[http://airspy.com/download> ." which links you to this wiki site https://github.com/airspy/airspyone_host/wiki/Troubleshooting#linux- debianubuntu I was able to install airspy-git, gr-osmosdr, and gqrx but I get lost on the part of blacklist the kernel >= 3.17 What can I do to blacklist the kernell driver? Thanks
