I read somewhere that aphantasia can be changed if one practises visualizing things by sitting with closed eyes, describing aloud to either a partner or a recorder what you want to see in more and more detail until an image actually develops. It shouldn't take more than a month with a similar time investment like meditation (i.e. like 20 minutes a day). Speaking out loud what you want to see seemed to be important from what I remember.
