If you want modifiers on your flow, you should not enable the particle interface. There is a limitation in max, that if an object is detected as a particle system, certain modifiers will become unavailable to it. That is the purpose of allowing the user to choose whether or not to enable the interface. Because when it is enabled, you will not be able to apply certain modifiers. And when it is disabled, you will not be able to use the tyFlow as a particle input to various 3rd party plugins that want particle inputs (PhoenixFD, FumeFX, etc).
There is no way to tell max to only apply a modifier to certain particles. However, you can differentiate the particles of your flow with particle groups, then create a second flow and import only the groups you want using Birth Flow/Flow Update, and then apply the modifiers to the second flow which only contains the particles you want modified.
