I don't think you can without first warming it enough to melt into liquid state. But solid fats usually don't need to be heated to much to melt. I think you should ask someone that makes it regularly for the best method.

Biodiesel is made using a transesterification reaction with an alcohol (methanol preferred). The reaction uses 3 alcohols per fatty acid and produces glycerol as a byproduct. Excess alcohol is needed (6:1 molar ratio) along with a catalyst. There are three pathways: acid catalysis, base catalysis (most common), and lipase. The primary reaction is easy, but cleaning up the end product for consistent quality, removing water and recovering alcohol takes some skill.
