I assume you are talking about some embedded system.  Remove the modules
under drivers/ except those that are used during normal operation. The
list of loaded modules is in /proc/modules.

I can imagine that some modules may or may not be used dependent on
the mode of operation (e.g. whether encryption is used), but they are
not under drivers/
