How to override a meta file definition?

I am using a 3rd party library for neovim runtime (neodev) which defines types for the global variables. There's a table which it generally annotates as:

---@meta

---@type table<integer, table<string, any>>
vim.b = {}

Is there way I can override this definition in my project scope as shown below?

---@meta

---@type table<integer, {autoformat?: boolean}>
vim.b = {}

The problem that I have currently is that the LSP infers vim.b[0].autoformat as any because the definitions annotate it as any|boolean.

Reproduce the example with neodev's global vim.b definition and the project-level @meta declaration shown in the issue. Start by tracing how LuaLS resolves competing @meta and @type declarations, then determine what supported override behavior would mean; the issue is complete when the behavior is implemented or clearly documented with a focused validation case.
