It is the opposite logic. "disable" overrides "enable":

        if not enable_drivers.contains(drv_path)
            build = false
            reason = 'not in enabled drivers build config'
        elif disable_drivers.contains(drv_path)
            if always_enable.contains(drv_path)
                message('Driver @0@ cannot be disabled, not disabling.'.format(drv_path))
            else
                build = false
                reason = 'explicitly disabled via build config'
            endif
        endif

In this case, you don't need to disable everything because of this:

if enable_drivers.length() == 0
    enable_drivers = run_command(list_dir_globs, '*/*', check: true).stdout().split()
endif
