Is there any way in FreeBSD to disable or enable devices on boot?

I tried it, but it immediately hung the computer, requiring Reset button.
Man page can be viewed at
Section on userconf is
-c Sets the RB_USERCONF flag in boothowto. This causes the
kernel to enter the userconf(4) device configuration man-
ager as soon as possible during the boot. userconf(4)
allows devices to be enabled or disabled, and allows
device locators (such as hardware addresses or bus num-
bers) to be modified before the kernel attempts to attach
