MXAO should be on if it’s part of the reshade presets or if that preset has a toggle for it you would just have to press whatever the toggle key is. You can always check for toggles by opening up your reshade menu!

For DOF, it’s generally different depending on the settings in the reshade here as well. I set mine to being mouse dependent. When you are in the “tab” camera mode in game, if you left click your screen it should bring your mouse cursor back up and then hover over whatever object you want to be the focus. Some presets use it as distance sensitive. For these ones it’s really more trial and error than anything. You just have to move the camera around until it puts what you are wanting in focus. I hope this helps!!
