The description for the helix knight transformation says that it is only open to agents that have "aquired all other sources of power" meaning agents who have bio-enchancement, TNI, martial arts training, and combat pilot training. That description made sense when those were the only trainings, but now that extra options like dagonization, blood boosting, gun kata, and others exist, could the description be updated to be more accurate?
Other trainings list exact stat requirements, so I don't think a more concrete explanation would be out of place
