I have the Acer Triton 500 and at stock the 2070 Super Max-Q use 80W, however there's an "Extreme" toggle in Acer Predator Sense software to allow the GPU to use 90W. This is not even documented in the manual, I figure MSI would have something similar so go into your MSI software to look for overclocking profiles.
Afterburner currently doesn't support power monitor nor increasing power limit on the Super Max-Q series yet, core/mem overclocking is still available though.
Edit: some quick overclocking with the 90W TDP got me 8k1
Timespy Graphic. At 80W I can get 7k7.
Edit 2: Seems like Asus Zepherus M is using the 90W version of 2070 Super Max-Q if you can find the bios.
