Time in the DLC (Alien: Isolation)

Passed the main campaign several times. The question arose: is there any way to disable the timer, or at least increase the time to perform tasks in the mode of Surviving? Is it possible to do this in the game files? If Yes, what is it?
Just Isolation play for the atmosphere, not for points, and a stupid timer ruins everything, forcing the player to run from a stranger, instead of intelligently and discreetly move around, collecting components to construct devices.
