If you prune the fronds off, they will likely not grow back. If you are ok with this, you can remove them with a sharp pair of pruners.
Thank you so much for your response. A neighbor cut back the entire Sago palm several years ago and the entire thing came back just fine. They are not from here and I was astonished when I saw what had been done. However, I am not likely to follow suit since our palms are so large.
