Is there anyway to turn raw input off without any option in the settings menu?

I have always turned raw input off and acceleration on to mimic the desktop windows mouse settings speed plus sensitivity ingame but there is no option for it and I know by default raw input is on because changing the windows sensitivity settings to low doesn’t lower the sensitivity ingame and the only option is to do complicated math like 1/11 windows sense equals .0909090901 ingame. Which is basically .1 mouse sensitivity but that is not exact.
