bbappends only work for recipe metadata not for config metadate space,
so no it wont be possible. You might BBMASK off the meta-ivi recipes.
ideally, its better if SOC layers append to such recipes from common
layers. So you might want to see if that is doable with your SOC layer
then you should propose a patch for your SOC layer to do so.
