rmmod command in Linux system is used to remove a module from the kernel. Most of the users still use modprobe with the -r option instead of using rmmod.
Syntax:
rmmod [-f] [-s] [-v] [modulename]
Example:
rmmod bluetooth

rmmod -v: This option prints messages about what the program is being doing. Usually rmmod only prints messages only if something went wrong.
Example:
rmmod -v bluetooth
-
rmmod -f: This option can be extremely dangerous. It takes no effect unless CONFIG_MODULE_FORCE_UNLOAD is being set when the kernel was compiled.

sudo rmmod -f bluetooth

rmmod -s bluetooth
