Server missing features EP4

[Hanji]

Hi guys, I'm actually working on a server and I'd appreciate if you could help me with some questions.

How to remove Mobtargetting with Tab Key.

How (if possible) to remove ignition.

Disable Dungeon Time or edit (maybe add one more DT for drop and or SP)

And last how to activate the "hardcore" server feature (i already followed a guide I found here with no success)

I'm not asking for a copy paste stuff (if possible would be great) but also maybe some guidance to start learning on my own.

Thank you all in advance.
