Can I use flexible metal conduit from a stub up to a fire control cabinet?
There is not a lot of information provided in this question. The NEC does address wiring methods for fire alarm systems circuits conductors. General rules for raceway installations are found in Part I of Article 760 and wiring methods for non-power-limited fire alarm circuits are found in Part II (specifically 760.46) while wiring methods for power-limited fire alarm circuits are found in Part III (specifically 760.127) of Article 760. Hope this information is helpful.
