It is not an utility, it is the featuer ti stop automatic trading if the balance/equity reaches ... for example $ 500.
I think - it may be for Freelance.
It's not possible (intentionally, by design) to remove or disable another expert adviser. EA can only remove itself. So you need to customize existing EA. Also, I think disabling trade in this EA does better suit your needs than removing it completely.
Maybe you can have it disable trading then all expert's will stop trading but check for all positions closed before okay.
