Well, the info that uname(1) prints out is generated from the source code at compile time. Recompiling the kernel, or updating the kernel via eg. freebsd-update(8) are the only ways to change it. If you're asking about the perennial "I just security-patched my system with freebsd-update, but uname still shows the old patch-level" thing, then yeah. Unless freebsd-update supplies you with a whole new kernel image, which only happens when a security bug involves the kernel, then the uname output will not be changed. It's a flaw, but any solutions involving being able to tweak uname settings without changing kernels open up a whole can of security worms[*] which are, on the whole, worse than living with some mildly outdated data.
