VR Game build runs at 60FPS with Steam VR( v1.11.11) on Alienware 15 R3. Built using Unity 2019.3.0f6

When I tried to run the VR standalone game build on the my laptop (Alienware 15 R3) it runs only at 60 FPS.

Laptop (Alienware 15 R3) configuration:

   Processor: Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz 2.80Ghz 
   RAM: 16 GB
   System Type: 64-bit OS, x64 based processor
   Graphics Card: GeForce GTX 1070

But the same build runs at consistent 90 FPS in another system with 16 GB RAM and GeForce GTX 1070.
I even tried the very small sample VR build, built by unity 2019.3.06f on my laptop, even it also runs at 60 FPS.

Our Game Unity VSync setting is - Don’t Sync

What could be the issue? Will, there be any setting that limits the FPS on laptops?

Update - 1:

For my game when I disable the G-SYNC in Nvidia Control Panel it’s playing at 90 FPS, but for other games even when the G-SYNC is enabled they are running without any jitter (90 FPS). How to achieve that for my game as well?

Update - 2:

When we tested the build of 2018.2.0f2, the game runs at 90 FPS, independent of G-SYNC settings. Like even if the G-SYNC is enabled the game runs at 90 FPS. But the problem is occurring in the unity editor we are currently using. 2019.3.06f.

Update - 3:
I even tried updating the unity version to 2019.3.12f1, the same issue is occurring with this version of unity as well.
