There are plenty of other MAX7219 libraries available: e.g. https://github.com/wayoda/LedControl

You can turn off aminations that you do not plan to use. Change the #defines ENA_* in the Parola.h header file. This is also documented in the library documentation.

Alternatively you can also just j=use MD_MAX72xx and write more code yourself to dosplay. There is probably an example that does this already.

If neither gives you enough extra memory, then you should use another library.
