Yes, you are right. I use different conf/bblayers.conf for different SOC.
But within the same SOC's different output
(board image, SDK), I just change MACHINE and SDKMACHINE. Is it safe to
build all outputs of the same SOC
in one build dir?

You mean I can't build two output with different DISTRO_FEATURES in the
same build dir.
Any other config var? What about MACHINE and SDKMACHINE?
