I tried to make update on NPScript and see if I can hide the hud other way...I could do it, but I was not able to restort the configured hud setting from ini back, instead it restores it to default one...I did not figure out how to change that, I guess someone else would need to code that...I am not that much into coding lately so...
Do not use this for online (one server already uses the npscript with the commented out hidecount, which is found in the npscript.zip and which is what should be used anyway unless this can be changed more properly), this is just unfinished test..just to show it was supposed to hide hud.
