DLC Question

Like many of you I recently purchased Lies of P since it will be getting removed from gamepass. I decided to sell my Xbox and just move forward with my ps5. So I’m replaying this fantastic game. Anyways, what do you all think is a good point I should play until? I’m concerned of going too far and locking myself out of DLC. Do you think it’s okay to go on the sub? Maybe stop before I beat Simon?
