Question regarding bktr driver

[Naram Qashat]

Well, I was wondering about something regarding the bktr driver.  If I don't
include it in my kernel and instead just use it as a kernel module, is there
a way to rebuild only that one module without rebuilding the entire kernel?
And would I need to build anything in the world, and if so, can I build that
without building the entire world.  Thanks.
