Autocmd to enter insert mode in terminal, but not in nnn.vim window

[jasoneveleth]

Right now I use:

augroup Term
    autocmd!
    autocmd TermOpen term://*:/bin/zsh call feedkeys("a")
    autocmd TermOpen * setlocal nonu nornu listchars= signcolumn=no scrolloff=0
    autocmd TermClose term://*:/bin/zsh call feedkeys("\<cr>")
augroup END

This will activate insert mode when you enter a terminal, and turn off numbers and stuff. But, these autocmds also fire when I enter into an :NnnPicker window.

How can I write an autocommand that won't fire when :NnnPicker is run, but it will fire on :te?
