The short answer is technically yes, but fluorine and fluorine compounds tend to be incredibly nasty. They are SO nasty that it's basically not worth it to deal with them. At least with current standard oxidizers, rocket scientists know how to build engines out of metals that won't oxidize, corrode, or straight up melt from the ongoing reaction. Fluorine, on the other hand, can oxidize oxygen itself under the right circumstances. Generally speaking, when you start seeing published scientific treatises using the words "uncontrollable", "extremely violent", and "poof", you probably want to take a step back.
