I updated your thread title, so that people can actually see what you are looking for . A VESC Mini is a non existing product, so no one can supply a FW for such a thing.
The supplier of this third party HW has the duty to supply the FW to you. It is Open Source and he would violate the GPL License if he would not deliver the FW in a timely manner.
My guess is probably this thing https://flipsky.net/products/mini-fsesc4-20-50a-base-on-vesc-widely-used...
You need to contact the manufacturer not ask on here.
