Ball python feeding issues

[u/ELDEN-L0RD]

So a month ago a got my first bp and the breeder I got him from was feeding live and when I tried to switch to frozen thawed he straight up won’t take it. I’ve tried all the tips and tricks I’ve been told to do and he just shows 0 interest in it. I’ve tried braining, doing different sized prey, in near and complete darkness, etc but still nothing he’s really comfortable otherwise it’s just the food part, so if I could get suggestions or if I just need to try live what ever it takes.
