Ammonia planet- atmosphere

On my previously asked question about the biochemistry of life on my ammonia. it leads me to my next question to ask.

First things first, the life on this planet is boron based. They breathe methane and drink ammonia. Due to their biochemistry being boron based. I realized that the gases such as bromine, chlorine, oxygen and fluorine can't be in large quantities as they form strong bonds with boron making life difficult to form. That however, leads to a big problem with complex intelligent boron life and their ability to make fire. In order to form fire you need three things. Fuel, an ignition source, and an oxidizing agent. Without those 4 main gases being in high quantity in this atmosphere, I lack a common oxidizing agent for life to use.

My question is, what gas in this alien atmosphere could be used as an alternative to those 4 oxidizers that wouldn't pose a threat to the formation of boron based life.

let me know if I got any information wrong in my scenario. I hope this is clear enough to be answerable.

Atmospheric composition if needed- nitrogen- 93% methane- 6% hydrogen- 0.2% other trace gases- ethane, diacetylene, methylacetylene, acetylene, propane, cyanoacetylene, hydrogen cyanide, carbon dioxide, carbon monoxide, cyanogen, argon and helium 0.8%
