How do I override a global keymap with a custom one?

nvim windows11

My simplified configuration is as follows:

vim.keymap.set({'n', 'v', 't'}, '<C-j>', '<C-w>j')
vim.keymap.set({'n', 'v', 't'}, '<C-k>', '<C-w>k')
vim.keymap.set({'n', 'v', 't'}, '<C-h>', '<C-w>h')
vim.keymap.set({'n', 'v', 't'}, '<C-l>', '<C-w>l')

require "lazy".setup{
    {
        "ibhagwan/fzf-lua",
        opts = {
            keymap = {
                fzf = {
                    ["<C-j>"] = "down",      
                    ["<C-k>"] = "up",      
                },
            },
        }
    }
}

I use <C-jkhl> for window navigation.
However, inside fzf, I want to use <C-jkhl> to scroll through the results.
Is there a way to achieve this?
Currently, <C-j> and <C-k> in fzf don't work unless I remove the global keymaps.

setup a filetype autocmd on ft=fzf
then vim.keymap.del them

Thank you for the reminder. I found a way to achieve this.

function autoKey(func)
    local act = func==vim.keymap.del and {}
    func({'n', 'v', 't'}, '<C-j>', act or '<C-w>j')
    func({'n', 'v', 't'}, '<C-k>', act or '<C-w>k')
    func({'n', 'v', 't'}, '<C-h>', act or '<C-w>h')
    func({'n', 'v', 't'}, '<C-l>', act or '<C-w>l')
end

autoKey(vim.keymap.set)

vim.api.nvim_create_autocmd("FileType", {
    pattern = "fzf",
    callback = function()
        autoKey(vim.keymap.del)
    end,
})

vim.api.nvim_create_autocmd("BufWinLeave", {
    pattern = "*",
    callback = function()
        if vim.bo.filetype == "fzf" then
            autoKey(vim.keymap.set)
        end
    end,
})

to avoid reset map u can set buf local map the key to itself on fzf filetype

            callback = function()
                vim.keymap.set('t', '<C-j>', '<C-j>', { buffer = true })
                vim.keymap.set('t', '<C-k>', '<C-k>', { buffer = true })
            end,
