Some general things I would incorporate; first perhaps try to add an appendage to address the situation directly, in this case you could just add my prompt to the end of yours and modify it to say “with an excuse based on the aforementioned persona rather than making references to AI”.
Perhaps also modify it to include “apologies” as per @_j 's suggestion.
Beyond this there are two things I’ve read and noticed makes a difference just for general prompt engineering; positive reinforcement being more effective than negatives (e.g. “do Y” rather than “don’t do X”), and something recent that seems to help in some cases is leveraging a sense of urgency, so if there’s a particular part that’s very important then you could add “this is very important for my career” or something to that affect.
