Is it possible to prefill a dropdown with only the logged in user's email?

In the settings screen for my app I have a dropdown that I would like the only entry to be the user’s email.
Other emails will be added to the same collection however the only data that appears will be the current logged-in user’s email.

Is this at all possible?

Just do a drop-down of users, where user email = current user email. And choose to display email field


Thank you, I appreciate your help!
