Help making supports for extremely detailed military truck model!

Good evening gentlemen,I am a newcomer to 3D printing and am trying to make replica prints of the trucks I and my platoon mates drive on a daily basis. However, the model I purchased is insanely detailed and even contains the undercarriage-- very cool, but hard to print as it has a lot of islands to contend with. I am using Lychee Slicer and my printer is an Anycubic Mono 6k Resin printer. Any help, and I really mean ANY help would be greatly appreciated as I'd like to print maybe 20 of these before I have to go back to base.
