Hotkeys utilizing <client_id>

My config automatically activates LSP for relevant buffers.
I frequently need to disable it when working with Helm (go templating doesn’t work with yamlls).
I would like a keyboard shortcut that disables the LSP when im in a Helm yaml file.
Alternatively, an autocommand that disables the LSP for yamlfiles when {{ is detected.

I would be able to piece this together myself if it wasn’t for the 'client_id` parameter. Is there anyway to obtain this programatically for the purposes of a keyboard shortcut / autocommand?
