The phrase "dost volition" is not a standard English term, and therefore has no established antonyms. However, "volition" means the act of making a conscious choice or decision, so antonyms for "volition" could include words like "indecision," "ambivalence," and "compulsion." "Dost," meanwhile, is an archaic form of "do," and has no direct antonyms - though synonyms could include "act," "perform," or "execute." In general, it's important to use clear, standard English to communicate effectively; using archaic or obscure phrasing can make it difficult for others to understand and engage with your message.
