You already own the monitor, so I Think it would be much faster for you to try out these settings by yourself and see if it works for you, than waiting for a reply on forums (I'm a bit busy).
Second, Vertical total tweaks do nothing if blur reduction is off, as it's a tweak to increase the vertical blanking interval period from 0.5 ms to around 4 ms (that gives the screen more time to complete a pixel refresh (which in turn, lowers the amount of strobe crosstalk (NOT to be confused with AMA/ghosting/overdrive). However, since the blanking interval is increased when the resolution is active, the monitor is being run way out of specifications. The Benq was actually designed to accept vertical total tweaking, while an identical panel (the Asus VG248QE) will instantly black screen out of range at any VT over the end of the lightboost range (around VT 1200). that's because lightboost mode uses an LC panel update to accelerate the scanout, to help the panel do a refresh faster. It's basically the SAME Thing as the VT tweak except its done through the LC panel, but the actual effect is the same (you can see it if you enable lightboost mode at 100 hz refresh rate and test the crosstalk at the bottom area of the screen and compare it to VT 1500 blur reduction (Strobe phase 000):

However when using a VT tweak, the panel is run out of specification and the scaler itself gets confused and thinks another resolution is running. This causes the "Display mode" aspect ratios to not work correctly and causes "Aspect" to suddenly be selectable at 1920x1080, because due to the increase in VT, the internal scaler thinks the monitor is being run at 1280x1440.
Using a VT tweak can cause a strange scanlines effect on the desktop, particularly on light backgrounds, due to the panel being run out of designed limits. This causes NO effect on lifetime or durability, but some panels may have a very obvious scanlines effect while others may not. Lightboost mode pushes the scanout even harder than a VT 1502 tweak does, so the scanlines will be even more intense in lightboost mode. This varies from panel to panel.
If this is a problem for you, you can create a custom resolution without the VT tweak, which will be at the same refresh rate.
The trick to that is, to make the refresh rate a fraction. e.g. 100.500 hz at 1125 (default) vertical total, or 120.500 hz. This was a popular trick during the Lightboost days when people didn't want the ugly washed out contrast and purple tint and wanted LB disabled.
Thanks for the answer. I tried to do the last thing you said but I can't create custom resolutions in the Nvidia Panel Control with fractions like 120.500hz
