Is it true that there is no way to disable vulnerable and unneeded device driver
built in GENERIC other that through rebuilding the kernel?

I remember that pre-4.x versions of FreeBSD had visual VGA-based pre-boot configurator
allowing to disable any compiled-in device driver. Don't device.hints(5) or loader(8) have means to do so?

These days GENERIC have LOTS of drivers and it's convenient but unsafe.
