You could always try tailscale until you figure something else out. Its not really self hosting but its better than having everything accessible to the public internet. Set it up in browser and follow their set up guide then install tailscale app on Truenas and whatever other device you plan on using it with.

I do remember reading somewhere that smartphones don’t have a standardized bootloader like PCs do with BIOS and UEFI, and that it can vary between manufacturers and devices. Could be wrong about it. Also some manufacturers really don’t want you to be able to install custom software, like Samdung in North America. If you buy a Samdung device in NA…even if it is carrier unlocked… the bootloader will be impossible to unlock.
Probably similar to how manufacturers tell you it’s for your own safety and “think of children!”
