How to set clients order with vim.lsp.buf.format?

Language Server Protocol (LSP)

In neovim 0.8, I find that vim.lsp.buf.formatting is deprecated. Use vim.lsp.buf.format { async = true } instead.
When there are multiple clients (such as eslint and prettier) attached the buffer, how to set clients order for vim.lsp.buf.format? (eslint format first, and then prettier)

I’m also looking for something to resolve this. I currently use eslint lsp for linting and prettier through NullLs for formatting. If I run them synchronously, it works find but it locks up the editor temporarily. If one of them is async they overwrite each other.
