I am unable to change my laptop Lcd refresh rate to its native 240hz rate.

When Big Sur boots up, it defaults to 60hz with no way to change it.

Is there a patch that I can add in the config.plist to remedy this issue.

It's a Lenovo legion 5i,
and I am using the open core bootloader.




Thank you.
