Considerations for a long-running Raspberry Pi
This covers the readonly filesystem, but doesn't cover the write protect flag that you can set on the microSD card itself[1]. The flag will configure the card's controller to drop any writes.
Also, creating a readonly root out of an existing disto is a bit of a pain, my preference is to use a distro (like TinyCore) that's already a readonly root.

SD card "Write protected" after removing it from Raspberry Pi 4.
There's https://github.com/BertoldVdb/sdtool. Although unlikely, maybe you can unlock the card with it.
