Lovely photo

She's gorgeous. And yes she might be a bit grumpy with the hot weather

Some dwarf hamsters do this unfortunately, but it can particularly be if a hand is in the cage as that's their territory. Is she the same out of the cage? Some taming could help though - you could try that. I think taming is better done out of the cage. Do you have a playpen or a bathtub? If a playpen is big enough, (or if you have a bathtub) you can sit inside it with her and she'll probably run over you as if you're a piece of furniture

And it can be a time for gradual handling as well. She will already be used to your scent and presence though, so a smaller area might be better to begin with and just focus on the gradual hand taming. Although it can be fun having a hamster running over you! I had a robo run up my trouser leg once
I'd suggest wearing a thick glove (eg suede or leather like a gardening glove) on one hand to start with. then you won't jump or react if she bites, then you can focus on gently saying "No". As a repeated thing. So maybe have your gloved hand palm up with some food on, and the back of your hand flat on the floor with your hand flat and straight generally. When she comes to eat food of your hand. You gently say No. And gently move your hand with the food on away again. Then put it back again. If she does the same thing again - repeat. She will start associating "No" with food being taken away (if she bites).
I used to do a combination of that and then just a bit of time letting them "play" in the playpen, maybe having a chew stick in there as well or something, and also the carrot cottages are popular (they like nibbling the top).
If you can start with a smaller area it helps (eg a bathtub but I know not everyone has one) as a large area straight away can be a bit overwhelming. But you could just block off one end of a playpen to make it a smaller area and then it's up to her if she wants to progress beyond the blockages!
Sometimes they enjoy exploring and wheel running in a playpen as well and then get into a different "mode" and she might be less likely to bite as she's having a different experience and distractions. She'll also get in the habit of coming out in a playpen and know what to expect. Do you have a "taxi" for transferring her? Using the same "taxi" each time means she knows she's going to the playpen if she hops into it.
So they can be "trained" to a degree.
