Allow InGame Control of Monitor Refresh Rate

The game locks frames to the monitor refresh rate.
Can you please allow the refresh rate to be controlled via the game/application?
I have a 240hz monitor and my frame rate locks at the same, which I can’t achieve.
I have to manually pull back to 144hz prior to starting the game but often forget to, which causes judder.
If the game could control the refresh rate I could set it up to switch itself in Nvidia control panel.
You could also allow us to set the frame rate to what we personally prefer instead of locked to the monitor refresh rate. This would allow us to set the rate to minus 3 of our achievable frames to refresh rate to minimise judder even more.
Thanks.
