You can do that by entering the service menu and turning on the "Single strobe" setting.
You can change the other strobe settings through the service menu.
The windows utility you are talking about is just a front end to communicate with the monitor's internal parameters through DCC commands. You can do the same thing with SoftMCCS (although the strobe settings are called strange names by softmccs, like 'parallelogram" and other VGA type names.
The XL2730z (note: XL2730z freesync version, NOT the XL2720Z) is lacking the single strobe setting. and the last I heard from Chief, he said he would contact Benq about it.
I can't give you direct feedback about the XL2430T as there has been little feedback about this monitor, other than the horribly broken "black equalizer 2.0" setting--leave this at "0".
A few people have uploaded pursuit camera screnshots of the XL2430T's blur reduction and overdrive artifacts. While some have been a bit blurry, they *seem* better than the XL2420Z and XL2411Z from what I can tell (the latter two Z monitors had really bad AMA artifacts in blur reduction mode! (the XL2720Z also has them almost as bad, but the V4 firmware AMA toggle fixes that right up). if this is the case, you should be happy with the XL2430T. But the AMA settings will still be worse than the XL2720Z with the toggle in V4.
This is the best thread I can find with someone who took pictures of the XL2430T.

There's another thread with images of the XL2430T.
You can see that they seem to look 'different', apparently much better.
But masterotaku suggested that this person was not taking "pursuit" camera pictures correctly.
I frankly would trust the first set of pictures as they look like what is expected with benq's overly aggressive AMA.
The following is XL2720Z V4 firmware with the AMA high toggle after blur reduction is enabled "aka AMA Low".
This is with contrast 0. You can compare the difference and see what you will like best. (these are all taken at 100hz in all examples, unless the above post said 120hz).
