How to set `cmp-zsh` completion source for `:!` commands (`nvim-cmp` stuff)?

Question

I have next setup for nvim-cmp cmdline : completion:

cmp.setup.cmdline(':', {
    mapping = cmp.mapping.preset.cmdline(),
    sources = cmp.config.sources({
        -- { name = 'path' },
        { name = 'zsh' },
    }, {
        {
            name = 'cmdline',
            option = {
                ignore_cmds = { 'Man', '!' }
            }
        }
    })
})

It uses zsh completion for paths and ! command, and cmdline completion for vim : stuff.

How it started: I have been using path and cmdline completion at the start of my journey, but I quickly found out that when I try to :!mv ~/Downdloads/file with spaces.txt ./file.txt I get no space escaping (file\ with\ spaces.txt) from path. So I added the cmp-zsh plugin. In the current setup with zsh completion source I have next problems:

• When I am writing some : commands I get the zsh and path completion. I want to get only path
• When I am writing some :!<command> commands, I get no completion for <command> because no shell commands start from !.

SO there is the question: How to make the zsh source be accessible only within :!<command> ... and disable path for :? As You may have noticed, I have already disabled cmdline for :! commands.

The :h nvim-cmp does not contain definition for :! mode. Actually, it says:

*cmp.setup.cmdline* (cmdtype: string, config: cmp.ConfigSchema)
 Setup cmdline configuration for the specific type of command.
 See |getcmdtype()|.
 NOTE: nvim-cmp does not support the `=` command type.

So, there is the getcmdtype() definition:

getcmdtype()                       *getcmdtype()*
      Return the current command-line type. Possible return values
      are:
          :   normal Ex command
          >   debug mode command |debug-mode|
          /   forward search command
          ?   backward search command
          @   |input()| command
          -   |:insert| or |:append| command
          =   |i_CTRL-R_=|
      Only works when editing the command line, thus requires use of
      |c_CTRL-\_e| or |c_CTRL-R_=| or an expression mapping.
      Returns an empty string otherwise.
      Also see |getcmdpos()|, |setcmdpos()| and |getcmdline()|.

It looks like there is no :! mode. Then how I can solve the

Partially solved with

            cmp.setup.cmdline({ '/', '?' }, {
                mapping = cmp.mapping.preset.cmdline(),
                sources = {
                    { name = 'buffer' }
                }
            })

            cmp.setup.cmdline(':', {
                mapping = cmp.mapping.preset.cmdline(),
                sources = cmp.config.sources({
                    -- { name = 'path' },
                    {
                        name = 'cmdline',
                        group_index = 1,
                        option = {
                            ignore_cmds = { 'Man', '!' }
                        },
                    },
                    {
                        name = 'zsh',
                        group_index = 2,
                    },
                })
            })
