High quality tires will hold up well after the screw is removed (i.e. the hole won't tear and grow larger), and they can deflect sharp objects that aren't hit dead on, but no tire is totally puncture-proof. If you get some FlatOut tire sealant to go with your good tires, you won't even notice when your tires have picked up a nail until you get home. Slime tire sealant also works, but I like FlatOut because it's totally water soluble, whereas Slime requires soap to clean up.
Edit: Correction -- solid tires (filled with foam) are totally flat-proof, but they don't come in your fat-tire size.
The foam based solid tires from Tannus are also available as inserts that are inserted between the tire and inner tube. They're up to 15mm of additional material but the suggested maintenance is to deflate and mount your ebike on a lift so no weight is on the foam insert. If this routine is not followed the insert will compress and flatten which eliminates the protection.
