Adjusting the amount of camera motion blur

My apologies if this has already been answered a thousand times, but is there any possible way to diminish the amount of camera motion blur being used? Sure, motion blur helps make camera movement much more realistic, but when animating for 24fps, the amount used when you check "motion blur" on the Maya2Octane module seems beyond excessive. The only way I can see to change it is to literally double the amount of frames I'm rendering (so each frame has 1/2 the amount of camera motion), then discard every other frame in post. When doing a 120 frame animation that takes 2 hours a frame as it is, I obviously can't afford to do that :/.

Thanks ahead of time for any help!

p.s. I would use a motion blur plug for AE, but it delivers inconsistent results at best if you're involving a lot of depth blur and don't have the time to render out separate layers for everything. Moreover, rendering a motion vector pass in Maya offsets the frames by .5 anyway, and takes additional time.

I totally agree, one frame of blur is too much sometimes, it's like we're shooting at 1/24 (in your 24fps example), which is a lot of MB.

Yeah, I just wonder if there's any way possible to change the amount of shutter open/close, and adapt that to the Maya export script?

Another experiment would be to turn the 120 frame animation into 240 as I said, but use the script's "By Frame:" option and put it to 2. Would that yield the same amount of blur as before, or would the blur be 1/2, which would be more desirable? I'll try it out with a lower-quality pair of comparison renders to test.

*EDIT* It works! Now the only thing left to do is find a batch re-name method so I can make these frames image.001, image.002, etc. instead of image.002, image.004...
