Can a region locked Switch 2 still be jail broken?

NOTE: This is not a thread discussing modding consoles or anything of that sort. Rather, the main topic is about the recent news on a guy who managed to hack the Switch 2 by adding third party content into MKW (which isn’t natively on the game) all because of a “game” found on the eShop (I think it got removed). He was using the global unit of the console. I’m ordering the region locked variant (日本語・国内専用モデル).

The difference between that and the international models are minor: mainly with the language and eShop, as the region locked one can only be used in Japanese and the JP eShop is only allowed (but would that alone be jail broken with hacks reverting a Japanese language only console adding other language packs basically turning it into a global unit despite this specific model being intended for domestic use only?).
