How to configure yamlls at a workspace level for neovim?

[V4G4X]

Summary

I mainly work with 2 types of YAML files. (In two separate projects)

1. Cloudformation Templates
2. OpenAPI 3.0.0 specs

And the inbuilt validator doesn't work too well with these. So I wanted to disable yamlls' validator for these two projects.

But the best I was able to do was disable it in my nvim-config, far from an ideal solution.

    lspconfig.yamlls.setup({
        settings = {
            yaml = {
                validate = false,
            }
        }
    })

I also tried configuring .vim/settings.json but that had no effect.
Please let me know how to configure this (or any other) LSP at a workspace level.

P.S: If it's possible to also specifically provide cloudformation schema or OpenAPI schemas for particular files/folders, that would be great!
But I digress.
