Heyo,
I would just leave the food where it is if you are worried about disturbing her, a lot of people scatter feed including myself, so i will just fill up a bowl of food and instead of putting it into the cage i will pour some into a few places around the cage so that my little ham has to go round and sniff it out which gives them a bit of enrichment
You could also do it while she's asleep as long as you don't disturb her nest. If i want to get into my hammys nest i always wait until the evening around 9pm he is usually willing to come out if i lure him with a little piece of broccoli
