>> My question is, how can I "instruct" lcms to use the B2Ax tables instead?
This is a feature I miss in LCMS too - as well as a way to tell the transform not to use any LUTs at all. I've seen LUT profiles that create terrible color casts so under some circumstances - so in these cases I'd rather use a given profile as matrix shaper than LUT. So more control flags would be nice. (At the moment I'm creating a profile copy and deleting the LUT tags....)
