The entire lower lot is a safe zone, so you're good there. If you have Early Entry or 2pm entry, you can head down there before any of the scarezones even open and you probably won't see them for hours. Simpsons is another safe zone -- they now have a scarezone in front of Studio Tour, so not sure how far that will go into The Simpsons area, but my understanding is not at all. There is a little side entrance to Wizarding World (another safe zone) that I could suggest you take, but my guess is Hellbullyz covers that spot. But if you go down that Simpsons row to Wizarding World, you would only encounter the Crowz which are fairly tame in scares. Chainsaw Man is also in this area. The other maze I know you want to hit is Fallout, so you could cross Murder of Crowz and go through Dia De Los Muertos (a non-scare party theme area) to get to Fallout, avoiding the main hub scarezone. If you want to get to The Purge show, you kinda have to go through the main hub scarezone, but I am sure by that point you'll be fine to get a jolt or two after going through FNAF and Fallout. To be honest, I have walked through scarezones hundreds of times without being targeted.
