A Pi4 and Pi5 know about GPT, so you can have up to 128 partitions per device. Just make sure you reserve 512MB or even upto 4GiB space at the beginning of a device (SD-card typically, NVMe is too complex for ROM code). So you can put hidden FATs there, bootloaders, ESP or 'RPi FAT'That's a good idea, but I would need to test how well the BSD handles booting off my NVMe drive. Disk encryption, if available, would also need testing.Just get a few more SD cards and try whatever you want. No need to erase a working installation.
You just need to understand how those OS loaders work, then it is rather easy to construct a 1st partition FAT32 filesystem to load an OS from some partition. If you need to rely on images, you will spent your time with guessing what you have downloaded and 'burned' etc.
