To deactivate the default animations, use this into Dino init (It works not for all):
_dino setvariable ["not_anim", True];

the Raptor doesn't attack anybody:
_Raptor setvariable ["not_raptor", true];

the Raptor doesn't attack only the Unit with these commands:
_Unit setVariable ["Raptor", true];
_Unit setVariable ["Dino", true];

The Raptor doesn't jump:
_Raptor setvariable ["not_jump", true];

The T-Rex doesn't attack only the Unit with these commands:
_Unit setVariable ["TRex", true];
_Unit setVariable ["Dino", true];
