You can try to use if() for the CONFIG options here. See for example
vid_console_color().

It is sometimes possible to do this, too, but it is a bit riskier:

switch (xxx) {
case SOMETHING:
    if (CONFIG_IS_ENABLED...) {
       do stuff if this feature is enabled
        break;
    }
    /* no break */
default:
    /* not supported */
}

Regards,
Simon
