No, I'm not aware of any options like that for the app.

It's strongly not recommended, but I guess you could do it via the desktop (or a regular browser on your phone), and just access robosats.com without tor. Here's the message that pops up when you do that:

"You are not using RoboSats privately To fully enable RoboSats and protect your data and privacy, use Tor Browser and visit the federation hosted Onion site or host your own app."

You'd really need to know what you're doing, in order to do this safely and privately. Use your own judgement, but be cautious.
