Hi. You dont need a MF if you are shure your scope/camera dont collide with your mount (or other equipment) or pier and your cables are long enough. I rarly do a MF, especially with my small scopes. Only if I'm imaging near zenite or at higher DEC values it is necessary, but depends on the telescope.

You can switch that in the mount tab. Just uncheck the box at "Flip if HA>"

If you are unsure, than watch your scope after the meridian passage, if there will be problems.
