If you want to focus on the mother plant and you don't care about growing the side suckers, you can cut them out now without any issues. The little suckers will definitely "zap" significant energy from the mother plant as they get bigger and they'll compete for light and nutrients. At this stage, it's unlikely that they'll have roots.

If you wait a few more months for the side suckers to root, you can cut them off and create new plants. It will be slightly at the expense of the mother plant, but in the big picture of things, it won't set back the mother plant that much.

Anyhow, If you take a very sharp knife and cut the suckers at the base of the corm with minimal damage to the roots, it shouldn't affect the mother plant under ideal conditions.
