According to Doctrine and Covenants Section 91
1 Verily, thus saith the Lord unto you concerning the ApocryphaβThere are many things contained therein that are true, and it is mostly translated correctly;
2 There are many things contained therein that are not true, which are interpolations by the hands of men.
3 Verily, I say unto you, that it is not needful that the Apocrypha should be translated.
This is referencing Joseph Smith's work in "translating" the bible. The work that lead to the Book of Moses and the JST version of the bible.
The takeaway here is that in the view of the LDS church, there is some truth in the Apocryphal texts, there is also some falsehood. Therefor it is easier to stick with the texts generally accepted as good by most followers of the Christian tradition.
