Option to disable spell checking and/or adding more languages to spell check in desktop app

I am bilingual user, writing down my notes and not just notes within the Bitwarden app in two languages - English and Czech. I like to have the user interface of all my apps and programs in English, but I still use both languages when writing. Spell checker for English works just fine in Bitwarden, but spell checker for Czech is not present, not even if I switch the app language to Czech.

To have a Czech spell checking (and not just Czech, I’m sure there are other languages with the same problem) would be awesome, but it is not a feature I find crucial to have. However, it is very annoying to see the red line below every word I type in Czech. I would find it sufficient solution if there would be an option to have spell checker disabled all together.
