What is a Chakra? If you examine old Tantras and ignore the New Age definitions, they are centres of conscious energy that represent different aspects that make the physical and energy body. They are not blockages or knots that can be “removed”. It is a concept of energy that can be utilized for cultivation or ignored. But how do you “remove” it and what comes of it? Does not seem to make sense to me.
When one is in Nirvikalpa Samadhi - aka Kundalini is refined completely, the consciousness resides in the Crown - one is considered fully Awakened and the lower Chakras are no longer significant. Such a state can be considered as “removal” - and that is the goal of most non-dual Indic practices.
