Re: Asus MG248Q
Variable refresh rate would require variable strobing. That is not something that officially exists yet. So no, you can't use freesync together with lightboost. No monitor exists yet that can do that. Some G-Sync monitors can be "hacked" to do it, but the results are not satisfactory.

The side effect is flickering during erratic frametimes. Some people are happy with it for a narrow set of consistent-framerate games that don't give erratic frametimes (creating erratic flicker). Also, it can be combined with high-accuracy RTSS framerate capping to create a low-latency 60Hz strobing that's a bit lower lag than the ULMB 60Hz hack (since it only has the more-minor capped VRR lag, instead of the bigger VSYNC ON lag) -- e.g. for use with emulators, or other 60Hz use cases.
But yes, the point, VRR strobing is currently extremely finicky and fits a narrow set of use cases -- and so you have to choose one or the other.
In the next ten years, the best way to have cake and eat it too, is future blurless sample and hold (strobless ULMB) via ultra-high Hz -- Blur Busters Law: The Amazing Journey To Future 1000Hz Displays. Fully flicker free and PWM-free method of blur reduction.
LightBoost tip: Try 100fps @ 100Hz LightBoost, if your framerates are unable to do full 120fps @ 120Hz. During LightBoost/ULMB operation, matched framerates 100fps@100Hz looks visually much better than 100fps@120Hz.
