Vim.lsp.buf.format notifications with disabled client

with the newest vim.lsp.buf.format, there is an option to disable formatting for a specific client.
Let’s say I don’t want to format specific languages at all.
If I disable formatting for a specific LSP (let’s say solargraph) according to the docs, each time I save ruby file I get notification about “[LSP] Format request failed, no matching language servers.”.
Is there an option to disable those notifications?
