How to unmap default mappings for Telescope plugin?

[LinuxIsCool]

How can I unmap these keys?

NvChad/lua/nvchad/mappings.lua

Line 66 in 156eeef

map("n", "<leader>fw", "<cmd>Telescope live_grep<CR>", { desc = "telescope live grep" })

In previous nvchad I had in mappings.lua:

---@type MappingsTable
local M = {}

M.disabled = {
  n = {
    ["<leader>f"] = "",
    ["<leader>ff"] = "",
    ["<leader>fg"] = "",
    ["<leader>fb"] = "",
    ["<leader>fh"] = "",
    ["<leader>fa"] = "",
    ["<leader>fm"] = "",
    ["<leader>fo"] = "",
    ["<leader>fw"] = "",
    ["<leader>fz"] = "",
  },
}
return M

Now I'm trying in mappings.lua:

require "nvchad.mappings"

-- Disable mappings
local nomap = vim.keymap.del

nomap("n", "<leader>f")
nomap("n", "<leader>fa")
nomap("n", "<leader>fb")
nomap("n", "<leader>ff")
nomap("n", "<leader>fh")
nomap("n", "<leader>fm")
nomap("n", "<leader>fo")
nomap("n", "<leader>fw")
nomap("n", "<leader>fz")

But getting error:

Error executing vim.schedule lua callback: vim/keymap.lua:0: E31: No such mapping
stack traceback:

Furthermore, how can I simply disable Telescope?

check the list of mappins in nvchad first, there is no such mapping as leader f

[LinuxIsCool]

I don't understand your answer. I linked directly to the mapping.

It's in NvChad/lua/nvchad/mappings.lua

And you can see it with whichkey as well.

there is no leader f here?

[LinuxIsCool]

I would like to unmap <leader>f as a prefix, thus I would like to unmap all those mappings that begin with <leader>f.

Vim.keymap.Del has nothing to do with prefixes , its which key stuff
