When you use /datapack disable <name> you can still call up the dialogs specified within that datapack by using /dialog show <targets> <dialog>.
I have seen and tested this in version 1.21.8, but it also probably affects earlier versions.

Dialogs are experimental, they require a world reload for changes to take effect.
