Can I downgrade iOS?

Not unreasonably, Apple doesn’t encourage downgrading to a previous version of iOS, but it is possible. Currently Apple’s servers are still signing iOS 11.4. You can’t go back any further, unfortunately, which could be an issue if your most recent backup was made while running an older version of iOS.
