"Forcibly" disabling a config option (CONFIG_BLOCK)?

[Ian Pilcher]

I need to test a kernel build with the block layer (CONFIG_BLOCK)
disabled.  Starting with a realistic configuration, I haven't found a
way to disable it, as it's selected by so many other options.

Is there any convenient way to "forcibly" disable an option (along with
everything that depends on or selects it)?

TIA!
