Two parts to my answer. First is to look at 350.10 uses permitted.
There subpart (3) says "For direct burial where listed and marked for the purpose". So it must be listed for direct burial before it can even be buried.
Then go to 300.5. LFMC is not specifically mentioned in any of the columns, but column 3 does say "or other approved raceways". So I believe if it is approved for direct burial that column 3 would apply or the specific conditions in column 4 or 5 could still allow you to use those.
