Can Mark Grayson (Invincible) stop the halo ring from activating?

mark grayson replaces master chief during the events of halo combat evolved. no relation but I thought it would be fun. for the sake of the prompt mark is fully allied with the UNSC. for the prompt let's say that mark is at the strength he's at by the end of season 2.

R1: mark doesn't have cortana aiding him R2: mark has cortana aiding him bonus: omni man replaces master chief
