Blacklisting Kernel modules
So first we open up our terminal. On most Linux systems you hit up this keyboard combination Ctrl + Alt + t, sometimes it's also your Windows key(i.e. Super key) + t, or you can hit this key combination Alt-F2 and then type the terminal name for example “gnome-terminal” or the equivalent in your system
sudo editorOfYourChoice /etc/modprobe.d/blacklist.conf for example
sudo nano /etc/modprobe.d/blacklist.conf
sudo vim /etc/modprobe.d/blacklist.conf
Or you can even use graphical ones
sudo gedit /etc/modprobe.d/blacklist.conf for example
sudo mouspepad -H /etc/modprobe.d/blacklist.conf for example
Then you go at the Bottom of the file add these lines
install module_name /bin/true fo example
install bluetooth /bin/true #disables bluetooth and its subprocesses
install btusb /bin/true
install uvcvideo /bin/true #disables your camera module and its subprocesses
blacklist iwlwifi #disables WiFi
blacklist firewire-core #disables firewire
blacklist thunderbolt # disables thunderbolt
Finally type these comands
sudo update-initramfs -c -k all
sudo shutdown -r now
To undo these steps you can just delete the entry or uncoment them and reboot your system
You can uncoment stuff like this, example
#blacklist iwlwifi
#install bluetooth /bin/true
Don't forget to save your new entries!
sudo update-initramfs -c -k all
sudo shutdown -r now
And then reboot
sudo reboot

Why it can be a smart idea to disable thunderbolt:
