CONFIG_ISA is entirely hidden on x86_64 these days.

Excerpt from arch/x86/Kconfig:

...
# x86_64 have no ISA slots, but do have ISA-style DMA.
config ISA_DMA_API
        def_bool y

if X86_32

config ISA
        bool "ISA support"
        ---help---
          Find out whether you have ISA slots on your motherboard.  ISA is the
          name of a bus system, i.e. the way the CPU talks to the other stuff
          inside your box.  Other bus systems are PCI, EISA, MicroChannel
          (MCA) or VESA.  ISA is an older system, now being displaced by PCI;
          newer boards don't support it.  If you have ISA, say Y, otherwise N.

...
endif # X86_32
