Additional context
Sorry, I'm viewing the document through translation read. For "At the top level, before any [[bind]] lines, the following keys are understood", I understand it as the first line setting, or setting before pasting

[[binds]]
ipv4 = "0.0.0.0:8080"
allowUnauthenticatedPermissions = { viewVideo = true }

[[binds]]
unix = "/var/lib/moonfire-nvr/sock"
ownUidIsPrivileged = true

Is my understanding wrong?
Searching for "repo:scottlamb/moonfire-nvr dbDir" found that "dbDir" keyword is only mentioned in ref/config.md, or the documentation is missing updates? Please help me look into it, thank you.

( Manually copying db files after executing SQL init is also not available

Sorry, I don't know why there was a problem with the layout

[scottlamb]

first line is [dbDir = "/mnt/data/nvr/db"]

I think you just have to remove the [ and ], and it should work.

For some reason all the blank lines had a U+FEFF (zero width non-breaking space, aka byte order mark, mentioned in e.g. this article) in them. I edited your comment to remove those and switched from ================ to ``` around the config snippet at the bottom, and it looks a bit better now.

thank for you edited.
first line:dbDir = "/mnt/data/nvr/db" , [ and ] The original intention was to use it as a boundary.
full "/etc/moonfire-nvr.toml":

dbDir = "/mnt/data/alist/nvr/db"

[[binds]]
ipv4 = "0.0.0.0:8080"
allowUnauthenticatedPermissions = { viewVideo = true }

[[binds]]
unix = "/var/lib/moonfire-nvr/sock"
ownUidIsPrivileged = true

I tried again but it still didn't work.
init and config Still using /var/lib/moonfire-nvr/db/db.
