I cannot directly provide a download link to the driver file itself, but I can give you the official solution and the correct source.

Here is how to get the correct driver for older macOS versions:

M-Audio discontinued the Axiom (first generation) and Axiom Pro series years ago. There are no official drivers for macOS 10.15 (Catalina) or newer (including Apple Silicon M1/M2/M3). On modern Macs, the Axiom 25 works as a class-compliant USB MIDI device without needing a driver.
