Some of these options are :

makeoptions            DEBUG=-g
options                WITNESS
options                KDB
options                DDB
options                GDB
options                INVARIANTS
options                INVARIANT_SUPPORT

They can be turned off by commenting them or removing them from a custom 
kernel config, rebuilding and installing that kernel.  Details on how to 
do this are in the handbook.  Note that as of 5.3, these have been 
turned off by default.
