What I can do is change 03 so you can only use the nades that you spawn with i.e two frag nades. That should reduce the nade spawn killing.
It is more difficult for it to be map specific but it can be done for all maps. Infinite ammo and nades would also have to be removed. Alternative is to use 05 which already has finite ammo and nades.
Could remove nade pickup on 05 if you like.
