A picture would help me so I'm only guessing
Originally I had pictured the holes near the inlet lip, a long way in front of the fan blades.
It would make a difference to me whether the holes are through holes into the hollow area of the inlet nacelle. If so they would affect the AI flow and increase the temperature on the inner skin near the holes. This could be to address run-back ice accumulation at this specific area in order to provide some protection against ice ingestion damage to the fan blade tips.
A lot more could be said about this, but since the purpose of the holes is only a guess .....
