Disable treesitter for latex

Hello,
I use the vimtex plugin for editing latex files. At start it tells me that highlighting is done by treesitter. How can I disable treesitter and use the highlighting of vimtex?

Thanks
Pawel

Update:
when I type

:TSDisable highlight

it does the job.

My question now is how do I do it automatically each time I open a .tex file.

Thanks

Use a FileType autocommand. For lua:

vim.api.nvim_create_autocmd({ "FIleType" }, { pattern = "tex" , group = optional_group, command = "TSBufDisable highlight" })

Maybe treesitter also has some kind of blacklist in the config, I can’t remember right now.
