you might add PREFERRED_VERSION to select the given recipe, in that
case recipe in your layer should have different version than the
original one. Then you can do something like

python () {
    if d.getVar("PREFERRED_VERSION_<pn>") != d.getVar("PV"):
        d.delVar("BB_DONT_CACHE")
        raise bb.parse.SkipRecipe("Skip it")
}


not too sure if it will ignore it. 

another option is to look at devupstream.bbclass it might have some
ideas for you.
