Pruning Cabbage Tree

Hi there,

I have a number of mature Cabbage Trees on the property which I like, but would like to “shape” a couple of them to stop limbs growing toward the balcony. I know from past experience simply cutting the limbs off will result in much thicker sprouting from the cut area.

Is there a way to treat the cut limb that will stop re-sprouting but not kill the tree? A friend suggested painting the limb with glyphosate but I’m not sure as I don’t want to kill the tree
