@NathanielOsborne - this is not a feature or setting that you can change. However, Microsoft do have something in Beta in terms of the ability to be able to change and update the email domain used. You can find out more here:
https://docs.microsoft.com/en-us/forms-pro/send-survey-email#customize-the-senders-email-address
It isn't something that all organisations will be able to take advantage of at this time, which is why it's not available as a live feature for everyone just yet.
If you use the Create an invitation step using Power Automate, you can then determine where or who the email is sent from.
