No there's no way to block it. I'm not sure what setting you're accessing so frequently that causes you to mistakenly activate the Reset Config option, but you can consider using the left button to go back rather than pressing the right button to cycle completely through the menus?
I'm actually working on the menu system currently to add some more stuff to it. I'll look at making it a double select option though so it you'd have to go to Reset Config? set it to Yes. Confirm by going to the next menu where it can prompt with an Are you sure? or something. Also maybe make it so the second screen prompts for what to reset like: Are you sure? "Cancel", "Yes", or "Full Reset". Don't hold your breath for that though!
