Hey,
You can take a few off, but don't go crazy and don't cut leaves out from inside the bud.
Cut early in the morning on a sunny day, preferably before sunrise.
If you cut leaves higher up on the bud, cut the petiole (leaf stalk) outside of the bud and when the stalk dies and dries up you can pull it out.
You don't want open wounds inside the flower now, that can be a spot for mold to creep in.
You don't have to cut anything unless you are worried about temperature fluctuation and humidity, so only do what you need to for better airflow.
