If your toddlers wake between 5/6 are they napping?

I feel like we’ve got into a vicious cycle of waking up between 5/6 and then needing to go to bed at 6pm every night because he is so exhausted. He hasn’t napped for months now but I’m wondering if I try and get him to nap will it reset him into going to bed later and waking up later? I’ve tried to do 1 hour quiet time during the day but he has unlimited energy during the day and continues to run around and play😂
