In my area (Kansas City), even with shipper designating "Signature required", due to COVID restrictions FedEx is NOT requiring or even asking for signatures. When they delivered my Galaxy S20+ and two months later my Note20 Ultra, both times the box was just left by the front door -- no knock, no bell ring, no signature.
If you won't be home, I suggest having a neighbor check for you every hour or so. Also, can you specify delivery instructions like "Behind the planter" or "underneath the rose bush" or "behind the porcelain statue." Anything to decrease possibility of porch piracy.
