I have figured it out, a little mod called Compass Marker Reducer is compatible, and to clarify what i was after let me just paste part from another topic where i have explained this:
As far as map markers goes, this was nearly game breaking in Nehrim for me. In Oblivion i didnt mind it as much, because the dungeons were numerous with almost no reward for completing, but in Nehrim you know that in those 10 dungeons out of 15 in the area is the set armor, so systematically clearing dungeons while you are scanning for their location from the road is killing the exploration aspect...in a game which one of the main focuses is on exploration.
thats pretty much it
