If you fix the cleats to your shoes on the side that they require a greater degree of heel rotation to release, and then dial up any tension settings on your pedals, that should be enough. Which side (Left or Right shoe) you install them affects release angle. I think the Right cleat (marked "R") on the Left shoe increases the angle needed to 17deg. Right on Right would be 13deg.
I usually unclip with my right foot. Whatever feels comfortable for you without sacrificing control and falling off.
If you're using ATAC cleats with mtb shoes with tread on the soles then they're designed for rough surfaces. The cleats are metal anyway. Road cleats which are soft and exposed and plastic, or the fiddly Speedplay ones, you don't want to be walking on rough surfaces with.
Check the cleats are securely installed and in the same position both sides. I always put a little grease on the screws. Not sure if it makes any difference. Install them in-line with the ball (back) of your big toe, which you can feel through the side of your shoe, and then move forwards or backwards a little if you need to from there.
