When "burning" one of these to the memory card, the resulting Raspberry Pi OS installation is installed without encryption: https://www.raspberrypi.org/downloads/raspberry-pi-os/
I've found out the hard and slow way that it's impossible to encrypt the disk after the "installation" ("burning" the image to the flash card).
Therefore, I'm considering instead using the installer approach: https://www.raspberrypi.org/downloads/noobs/
However, since this means setting up a monitor and keyboard and everything, I can't test it easily.
None of the videos show anything useful, such as going through what "NOOBS" actually looks like and what options it presents. The text description mentions nothing about encryption.
Does this "NOOBS" installer allow me to select for it to encrypt the disk so that it requires a password input on every boot and nobody can steal my RPI and/or its flash card and read the contents of my OS/data?
