remove kernel modules debian

hi i want to remove bluetooth /wifi / and the built in broadband modem / netbios .on my laptop how would i do this ? / i had a look in /lib/modules and cant seem to locate bluetooth / would it be in my root directory.

do i just rhmod -r /lib/module/"module_name"

or is it easier to do modprobe ?

sorry for all the questions new to linux.
