The only solution I can think of is using it via API with Python and make a call with the final reply asking it to remove apologies from the text, but the token usage will increase.

I do something similar when I need to tell the model to keep the language of a text before performing a task with that text. I send the model a chunk of text and ask it to respond with single word, indicating the language of the text and then I include that in the next prompt like "Your output must be in SPANISH", or whatever.
