I just want to ask if will it boot if i will downgrade from EU LATEST WEEKLY ANDROID 11 to EU STABLE ANDROID 10 without formating the whole internal storage (the one where you need to type "yes" in the recovery) but i will clear the system dalvik cache.

I don't have much time for now to backup files on my internal storage that is why i think to flash like this.

Why? Are you sure it will not boot even i wipe system dalvik cache?
You can't expect to be able to downgrade Android 11 to Android 10 without a data format...
Downgrading is not a supported operation on Android in general...
