You can mark them so you know which ones are older and which are newer if you don't want her to hatch so many, and then once she stops laying and starts sitting you can remove a few.
I don't think removing the eggs will impact if she does or doesn't keep laying. I remove my duck eggs every single day and they lay me new eggs the next day. They are however slowing down for winter already Today I got two eggs from my spring ducklings (just started laying this past week) and zero eggs from the older girls who were giving me eggs all summer.
