This is useful to turn off explicit module load and unload operations on modular kernels. This option removes CAP_SYS_MODULE from the capability bounding set for the unit, and installs a system call filter to block module system calls. This option will not prevent the kernel from loading modules using the module auto-load feature which is a system wide operation.
