You can use vidcontrol to do that.

At boot? Never tried this, but I think there are some kernel
settings that are relevant for this; they'll be documented in
the NOTES files for the kernel.

In FreeBSD, use the Scroll Lock key (that's why it's there); the
length of the scrollback buffer can be controlled by vidcontrol, too.

Refer to "man vidcontrol" and its EXAMPLES section.

Make sure the requested videomode is available, "vidcontrol -i mode"
will tell you.
