Framerate ?

If it is set at that, yes. But it ultimately depends on what your interface delivers. And bitdepths are always in whole numbers anyway. (either 16 or 24).

If you don't set a bitdepth Logic will take what it gets; so if it gets 24, it'll take 24. If it gets 16 it'll take 16. However, if it set at 24 it will "upsample" any 16 bits it gets to 24 (which has zero soundquality benefit, actually.)

What does 24 bit have to do with it? That is something completely different than 24 fps. And fps is irrelevant if you do not work with movies (fps is frames per second, a VIDEO setting)

Because that is in the template?

So, open the template, change that, and resave as a template with the same name.
