There is no way to just tell the keyboard to ignore these keys.
As far as the keyboard is concerned, they are just another key,
the BIOS gives the key meaning.

One way to surpress these keys is to write a small TSR routine
that sits on INT 9 (the interrupt the keyboard generates whenever
a key is pressed or depressed).

This routine would pass control down to the next levels in the INT 9
chain via a routine call (not a branch). Then when control perculates
back up via the lower level IRETs, you would clear the keyboard
status word bits at 40:17 for the NumLock and CapLock.
