I don’t think you will be able to track method level grants through History log. Probably for the best as these are tracked through base security sys tables and can become a massive overhead if logging is setup on those.
You would however be able track pres Object level changes against permission sets by setting up logging on PRES_OBJECT_GRANT_TAB. Once again, be vary on the overhead if you are doing lot of changes to security.
You could try out a custom event (PRES_OBJECT_GRANT_TAB) for this matter since it records old value and new value. You can just record these values along with the session user and timestamp to a table you created.
