Is there a way to hide cursor when nvim-tree window is focused? It's purely cosmetic, I want to rely on CursorLine highlight and make the cursor invisible in nvim-tree window.

You can achieve that by some auto commands, I used to use those.

{
  event = { 'WinEnter', 'BufWinEnter' },
  pattern = 'NvimTree*',
  callback = function()
    local def = vim.api.nvim_get_hl_by_name('Cursor', true)
    vim.api.nvim_set_hl(0, 'Cursor', vim.tbl_extend('force', def, { blend = 100 }))
    vim.opt.guicursor:append 'a:Cursor/lCursor'
 end,
},
{
  event = { 'BufLeave', 'WinClosed' },
  pattern = 'NvimTree*',
  callback = function()
    local def = vim.api.nvim_get_hl_by_name('Cursor', true)
    vim.api.nvim_set_hl(0, 'Cursor', vim.tbl_extend('force', def, { blend = 0 }))
    vim.opt.guicursor = 'some (most likely default)settings'
 end,
}

You can probably just set up window local highlighting now. Not sure.

This is awesome! Here's how to do it using vim.api.nvim_create_autocmd with the default value for guicursor:

vim.api.nvim_create_autocmd({ 'WinEnter', 'BufWinEnter' }, {
  pattern = 'NvimTree*',
  callback = function()
    local def = vim.api.nvim_get_hl_by_name('Cursor', true)
    vim.api.nvim_set_hl(0, 'Cursor', vim.tbl_extend('force', def, { blend = 100 }))
    vim.opt.guicursor:append('a:Cursor/lCursor')
  end,
})

vim.api.nvim_create_autocmd({ 'BufLeave', 'WinClosed' }, {
  pattern = 'NvimTree*',
  callback = function()
    local def = vim.api.nvim_get_hl_by_name('Cursor', true)
    vim.api.nvim_set_hl(0, 'Cursor', vim.tbl_extend('force', def, { blend = 0 }))
    vim.opt.guicursor = 'n-v-c-sm:block,i-ci-ve:ver25,r-cr-o:hor20'
  end,
})

FYI a new configuration option has just been added: :help nvim-tree.view.cursorline
