Any up to date guides for Secure Boot and Flash Encryption?

[david_hambo]

I've had no end of issues trying to follow along with older guides with both PlatformIO and ESP-IDF toolchains to get Secure Boot and Flash Encryption working with an ESP32-S3 project with Arduino libraries.
I went back and did a blank install of ESP-IDF with v5.1.3 ESP can't even compile the Arduino demo project.

Are there any up-to-date guides for using Secure Boot and Flash Encryption with a project that is using ESP32 and Arduino?
Preferably with the PlatformIO framework.
