That's post-processing, the dev didn't put the option to disable any of them, even though Unreal has quite straight forward examples of options menu with all of them included to be toggleable.
Blame the dev, it's a extremely awful game UI. I for example loathe the stupid choice of putting fucking sliders as options and NOT ALLOWING the user to set precise integer numbers. Fucking slider starts with 1 as default, you change it to experiment and it goes float to something like 1.027... and then you can't put it back to fucking 1 EVER again. Fuck that, it's infuriating as fuck.
