Since the even release of the Update Aquatic, i have never seen drowned spawning with enchanted tridents in Bedrock Edition.
This also trigger a inconcistency with mobs that are able to spawn with enchanted weapons/tools, because:
Zombies can spawn with enchanted swords/shovels.
Skeletons can spawn with enchanted bows.
Pillagers can spawn with enchanted crossbows.
Vindicators can spawn with enchanted axes.{*}{*}
Any mob that is able to spawn with armor has a chance of getting the armor with enchantments.
However, drowneds are not able to spawn with enchanted tridents.
Observed:
Drowneds cannot spawn with enchanted tridents.
Expected:
Drowned should be able to spawn with enchanted tridents.

Vexes also do not spawn with enchanted swords. I think this is by design, as drowned with enchanted tridents might be too powerful or the trident-specific enchantments could not be made to work with non-player mobs. The way trident-throwing drowned work now is like they have the loyalty enchantment.
Maybe indeed the drowned counterpart be intended, but in java edition, vexes are able to spawn with enchanted swords, even fire aspect ones.
Also, enchanted tridents do not work for drowned as per MC-127321
They also don't spawn with enchanted armor. This works the same as in the java version and probably works as intended (but I don't have the source).
