You need to nail, clamp or screw a flat board onto the log in such a way as to prevent the log from rolling into the blade. I can’t explain quickly. I’ve never done it. There is a LJ who hurt himself badly trying to slice a log on a bandsaw.

Cutting rounds on a bandsaw comes with HIGH RISK SO BECAREFUL.The blade will pull the roundness forward very quickly and with a lot of force. The blade will be trashed if this happens.
It can be done safely with a good fixture.
